Pranks

To celebrate their tenth anniversary, Improv Everywhere is releasing remastered videos of their best stunts. First to get the treatment is the classic Best Buy prank in which 80 Improv Everywhere members enter into the Manhattan Best Buy wearing blue polo shirts and khaki pants, the uniform of a Best Buy employee. Watch it in HD after the jump.

Brian is able to terrorize his coworker with the same clear-tape-across-the-door prank over and over.

A prankster wears an authentic old man mask and proceeds to (fake) fart on Target shoppers. Responses range from mildly amused to profoundly annoyed, but all are extremely amusing to watch.

Improv Everywhere founder Charlie Todd pranked the guests at his wedding to fellow troupe member Cody Lindquist by having a pro wrestler interrupt the ceremony during the "Speak now or forever hold your peace" part.

Joey didn't like the way he was treated during his three-and-a-half year tenure at Rhode Island's Providence Renaissance hotel. So when it came time to quit, he decided to really rub it in his boss' face by bringing along his 19-piece brass band, the What Cheer? Brigade.

When a couple of pranksters decide to unleash some very juvenile fake farts around their college campus using a toy called the "Pooter," the reactions of their victims prove far funnier than the cheese-cutting itself.

A dad's attempt to sneak up on his daughter and frighten her ends in hilarious failure when he slips on a wet driveway and lands on his face. Watch the prankster pop take a tumble below:

Pittsburgh Steeler safety Troy Polamalu recently posed as a wax version of himself at Madame Tussauds in Hollywood. Then he freaked out visitors to the museum by coming to life. Our favorite part (as in all prank videos) is when the kids think they are about to be eaten.

This fellow fell asleep on the job. As you can see (and hear) in the video below, his punishment was being awaken by a coworker's blood-curdling yell. Pretty sure that move isn't in the employee handbook.

Prankster Ellen DeGeneres teamed up with 'Today' anchor Ann Curry to pull a fast one on an  unsuspecting elderly woman at Universal Studios.

With help from Sharon Osbourne, Howie Mandel played a truly hilarious (and somewhat disturbing) prank on a sleeping Piers Morgan recently, he said on 'Conan.'

Australian humorist David Thorne, best known on the internet for trying to pay a bill with a drawing of a spider, has taken his mischief to the workplace. His elaborate pranks on coworker Simon Dempsey include replacing his business cards with ones that list his position as "Horse Whisperer" and tediously painting his black iPhone white with Liquid Paper. Thorne recently posted scans of

There's no doubting the ease and creativity with which this gentleman avoids an oncoming train. Courtesy of UK based YouTuber BlackMoonCGI (who had a hit video a few months ago with his take on what's inside Dr. Spock's scanner), with this instructional video you'll never get stuck with your car on the train tracks again.

What could be better than working at Legoland? Pulling a Lego prank on your boss, of course. Employees at Legoland California built a full-sized replica of general manager Peter Rochetti's car out of the colorful blocks. Made out of 201,076 Lego pieces and weighing in at 2,934 pounds, the copy is an almost identical likeness to Rochetti's Volvo XC60. Watch the caper (and the big cheese's reaction)
