A girl walks into a room and is greeted with an air horn. Her reaction isn't quite what you'd expect.

This one is pretty gross. This kid got a spider bite on his cheek, and as a gift to us internet folk, decided to squeeze it on his webcam.

I bet he could have gotten away with taking a leak on one of the girls legs.

Some guys have no shame, this one pranks a live newscast about a raging fire to show his support for Howard Stern.

If it was done a week after the movie came out, maybe it would have made some of these pre pubescent kids cry.

This is one prank that never gets old, and possibly gets even better with time. Funny thing is, most people would end up stuffing it in their pocket and not caring.

Friends, what are they good for? Absolutely nothing to this kid.

Yet another reason I never want to work in an office building.

I'd imagine this is not a prank you should try at home - this guy looks like he has some serious burns!

What's so bad about this? It's like having your own theme music wherever you go.

Sure its funny now, but they wont be laughing when hes taking a dump on all their faces in their sleep.

This is one of those times the word "revenge" gets thrown around in your head a couple thousands times a day.

Here's another clip of one of the funniest pranks you can get on tape, except this one draws a lot of blood in a little amount of time.

If you ever think it's a good idea to attempt this prank, make sure to watch this over a few times and rethink it.

I don't know about you guys, but I would pull into the place to acquire additional information.

The only thing that startled me was the fact that the black dude didn't shoot the white dude.

Air horns aren't just for basketball games anymore.

If you ever come into the possession of 500 golf balls, and have no interest in the game whatsoever, here is an idea.

That dude who got pranked while taking a dump, gets his revenge here by hiding in a freaking fridge.
