pranks

Here's a little gem from the TruTv reality show 'Principal's Office.' We aren't really sure how the principal thought it was going to go when he brought in two student "leaders" to ask them for help solving the school's "grinding" problem, but this seems about right.

Here's a little video to get you into the spirit of Christmas, if you're kind of trampy. Nate, Caitlin and Stuart set up shop on the campus of Brigham Young University to trick as many people as possible into kissing them by using a sprig of renegade mistletoe that drops down at a moment's notice. They are braver than we -- the whole time we watched this all we could think was "Herpes! Herpes

Just because it's legal to do it on your own time in Colorado, doesn't mean you can drug your whole class. Two University of Colorado students in Boulder thought it would be funny to bring pot brownies to a morning class to share. Then a bunch of people who ate them had freak- outs. Suddenly it was not so fun.

Ghastly little children and zombie corpses in elevators aren't the only things petrifying people around the world this holiday season. It looks like even Frosty himself is getting in on the act to wish us all a very happy (and spooky) holiday.

Think last week's ghostly elevator prank was tormenting? Think again, because it turns out that ghoulish little girl of yesterday was only the beginning. All Hallows Eve might have passed on the calendar but the undead elevator prank is always good for a scare.

If you like watching people being frightened, this is the video for you. A man and his cameraman friend set up shop in an alleyway near Chicago's DePaul University. The guy was dressed up like Slender Man, a creepy faceless man/internet meme...

Few things are most satisfying than pulling off a really, really good prank. We're talking about the scare-your-pants-off kind that leaves our unsuspecting little siblings and friends falling victim to tons of spazzing out and the occasional tear or two. Basically, it's the best kind of mean joke around, but it's all in good fun!

If you haven't seen 'Toy Story 3,' you should probably stop reading and not watch this video. But if you have, you would know that at the end of the movie Buzz Lightyear and friends face certain death via fiery incinerator, only to be saved at the last moment by a giant claw. Some pranksters decided to have fun with the movie's ending and the target of the prank was their poor unsuspecting mother.

Teenagers are the worst. If you need further proof, just look to Ogemaw Heights High in West Branch, Michigan.

It's one of the most artistic pranks we've ever seen - this car was spotted covered with Post-It Notes in the parking lot of Barnes & Noble at Consumer Square in New Hartford earlier this week.

We see people holding hands all the time, with the assumption being that the pair know each other. But the pranksters of LAHWF have put a new twist on the gesture of physical intimacy by walking up to random folks and taking them by the hand. Check out the video results of this interesting sociological experiment.

Justin Bieber, a self-styled prankster (something we’ll see more of on tonight’s season premiere of the resurrected ‘Punk’d'), may be able to get off easy regarding the headache he caused as Texas grandmother regarding a phone prank.
