Now that’s a prank! And he did it all afternoon!

We’re just glad no one had a heart attack when Arnold Schwarzenegger decided to visit Madame Tussauds Wax Museum and stand in for his own wax figure just to scare people.

One person on a tour of Microsoft decided to prove he was there by taking a photo in front of a plaque.

But Bill Gates made sure he really had something to show his friends by appearing in the background of the photo.

NOW we believe him.

This is one of our favorites just because this kid can never live down the fact that he fell asleep in front of the president.

Once Obama saw him snoozing, he headed over to make sure he had a memento of his nap!

When one high-schooler decided to take a cardboard cut-out of Danny DeVito to prom, he heard about it and decided it went well enough to warrant a second “date.”

He had a cardboard cut-out of her made and showed her around town.

Can you imagine?!

This kid probably won’t remember meeting Bill Murray, partly because it didn’t really appear to him at the time.

But the actor decided not to let the kiddo cry alone.

And now the photo is really something to remember him by!

After sending a headshot with her fan mail to Tom Hanks, a woman was shocked to see that he not only replied but did so in kind – with a photo of the two of them “together.”

Not only do we love his stationary, we adore his sense of humor.

Hey, if people are going to use your name to get customers, then you might as well go collect your free meal, right?

We hope he tipped well because rumor has it that he collected on that promise!

We’re not sure when or where this set was, but you have to love The Rock gracing the background of a fan photo.

That would be our Christmas card every year for a decade if we had been so lucky.

And the actor’s expression is just epic.

Chris Pratt fans begged him to post photos of himself with Jennifer Lawrence when they filmed a movie together and went on a press tour.

He happily obliged – it’s just that he either cropped her out of or blocked her face in every photo.

Guess the fans should have been more specific!

While filming Pirates of the Caribbean, Johnny Depp decided to walk around Queensland one day in full garb.

Depp had been in some hot water for coming into the country without quarantining his two dogs first, so fans were a bit riled up when he happily posed with law enforcement.

This is too funny.

No harm was done, but The Rock likes to pretend he’s signing people’s heads when they ask him to sign their shirts.

And by the looks of it, this little fan was truly taken aback!

When you’re a celebrity, people like to try to take photos of you in public.

Actor Cole Sprouse is onto them.

In fact, he’s devoted an entire Instagram account to taking their photos as they try to take his!

Looks like Gwenyth Paltrow hasn’t forgotten how harsh everyone one about her decision to name his daughter Apple.

She made it clear to Elon Musk and any fans reading that she expected to stop getting crap for that after he and his partner named their child X Æ A-12.

Rhianna fans would ask for new music every day if they could.

But the singer and cultural icon is telling them to hold off a little on the pressure.

Good things come to those who wait.

It’s hard to call it a troll when it’s such a remarkable win for everyone involved.

When a fan asked Ryan Reynolds to help him wish his wife a happy anniversary.

The Riverdale actress goes full throttle on social media when people get under her skin.

And she really went right for these mean girls, who we can only hope learned some kind of lesson as the real trolls in this situation.

After being body-shamed, she once again had the best comeback – and a cheeseburger.

It’s pretty clear who the winner is here.

Ryan Reynolds pulled a Chris Pratt on fans when he cropped his glamorous wife Blake Lively out of a photo celebrating her own birthday.

That’s true love.

We have the feeling these two spaced themselves juuuust far apart enough to get Gyllenhaal in the photo once they saw him in the restaurant.

But he was a good sport – not just to look up but look up with just enough exasperation to let us know that he knows what’s happening here.

You know your marriage is blessed when Jason Momoa is on the same beach as your ceremony AND agrees to photobomb your wedding pics AND there happens to be a kid on the beach with a trident he can borrow.

Seriously, we’re jealous.

Celebrities – they’re just like us! Even January Jones can’t resist a little mockery when it comes to kitchen accessories.

That fruit is making us jealous.

Ok, calling this a troll is a stretch but how could we not show it to you?

When this guy asked to take a photo with Fabio, the model went all in.

You know what’s sexy? A sense of humor.

Hey, when a tabloid is in it for this kind of info, you have every right to dish it back.

Sure, it was a little dirty, but they started it!

We love an athlete who loves their fans, so we think Matt Garza getting in the back of this photo is super cute.

And we’re pretty sure this is the kind of prank she was happy to be a part of.

Hey, even Sharon Stone gets bored.

She’s scrolling through Instagram giving a high-five to people empowering women.

Of course she doesn’t need validation, but she’ll be happy to joke about it.

Just like we think that couple knew full well that the actor was behind them for their “selfie,” we’re pretty sure by the angle of this photo that this young women knew she’d be getting a bit of actor Michael Cera.

If he REALLY wanted to be a troll, he could have done something rude. But he met the challenge with a head-on stare.

First of all, don’t try to tell Cher anything. Like, who even are you?

Second, fully expect Cher to clap back if she bothers to acknowledge your existence at all.

She’s Cher, and she can type in all caps if she wants to.

Don’t you hate when you post a pic with your bestie online and your mom (actress Leslie Mann) logs on just to critique your makeup?

SO embarassing!

And yet, mom’s right.

We laughed, but we could imagine a better troll here from Pauly D.

Or perhaps we’re missing Snooki’s deft slight on the mom culture that requires moms to put an Etsy-fied number next to their babies to celebrate each month of life.

We kind of hope so, because that’s the only way the Post-It is funny, making Snooki the true troll here.

After a heartfelt post by her stepmom, Ireland Baldwin shot back lovingly.

We love a bit of sarcasm, especially from celebrities.

It shows they don’t take themselves too seriously.

Ok, so everyone is creeped out by this Jonas Brothers face swap. It’s eerie.

But the fact that mom got on there to say she hated it AND that Dr. Phil randomly chimed in to agree was just too good.

Not THAT part we love.

Oh snap. Don’t you hate when you’re just trying to be a rich and famous teenage stud on social media and your dad logs on to ask why you’re not at school?

I mean, it’s never happened to us, but we’re sure we’d be embarassed.

Was Seth Rogan trolling himself when he said he and his wife Lauren Miller were basically the poor man’s Timberlake and Biel?

But how does the little dog feel about this?

Mess with someone succesful? Ok, but then there’s really nothing you can do when they point out why they’re famous.

One of the members of Fifth Harmony decided to troll her troll a few years ago. And the first troll went and deleted her account.

We don’t even know how a person gets so lucky. First he meets Beyonce, then she agrees to take a photo with him, AND she agrees to make faces.

Posting this amazing photo is the best way ever to troll your friends in the biggest feeling of FOMO ever.

Cindy Crawford’s mini-me model daughter decided to give fans a laugh when her mom posted a racy photo online.

To be fair, we bet dad didn’t really love that photo.

That has to be some sort of good luck, right?

We don’t know if they decided to take some new Chappelle-less photos, but we don’t see why they would. Who wants to see those?

To be fair, you can’t swing a sweaty, fringed handbag at Coachella without hitting a celeb, so is it really a surprise that there’s be two in the background of your couple selfie?

Luckily, Aaron Paul and Kellen Lutz weren’t in full troll mode.

Celebs are going to have big engagement rings. That’s just how it goes.

But pointing out that they’re flaunting it seems a little petty.

Luckily, actress Sarah Hyland doesn’t mind being called out.

Looks like someone thinks it thier business to protect a celeb’s kids from photos of their parents.

We’re pretty sure most teens know mom and dad sleep in the same bed.

But Kelly Ripa admits to having an Instragram account for the sole purpose of trolling her kids anyway.

A Tim Horton’s coffee seemed to get a fan in a steamy mood towards Canadian Justin Beiber’s Instagram stories post.

We think she was probably looking for a sexier comeback, but she’s going to be waiting a while.

If you want to take a fan photo with Elijah Wood, be prepared to do some heavy lifting.

He’s got the weight of the world on his shoulders carrying that ring and all. And while his fan can’t carry it for him, like Samwise, she can carry him.

Why do fans write these sorts of messages and not just log off and go away?

Singer Kacey Musgraves shot right back and gave us all some good ammo to use in the process if anyone ever insults us like this.

People really got into the meaning of the word “photobomb” on this post.

And since it’s a made-up word, there’s bound to be confusion.

Do you think this is a photobomb just because they weren’t expecting his expression?

No, Hanks didn’t prank some completely wasted guy in a bar.

As the original title reads: “My friend met Tom Hanks, stole his glasses and pretended to be wasted.”

We’re just surprised Hanks went along with it!

John Mayer only asked what anyone who thought about this photo for more than a few seconds would wonder. Who took the photo?

Kind of a weird job to be a hot tub photographer.

Hey, we need as many reminders as we can get to bring our masks along.

No one loves wearing them, but Demi Lovato just wants to make sure we don’t forget.

We’ve all been there. Lazy afternoons during a slow time at work or late at night…you’re just scrolling around and you see a weird post and can’t help but respond.

Ok, we can usually help ourselves, but celebs don’t have to since people seem honored to have them make even a snarky comment.

Different strokes for different folks, we guess.

This sounds like a pretty trashy move to us (really, it sounds funny at first, but think about what this really involves).

Nevertheless, Spears wants to know what’s so bad about it.

Public intoxication, for starters.

Lately, Dionne Warwick of all people has been taking over Twitter and snarkily dragging other celebs – and plain old users.

It’s been quite a sight to see and she seems to be really enjoying trolling people. We can’t stop looking!
