Improv Everywhere

It's something only Improv Everywhere could accomplish -- going on to a subway car, making a huge ruckus and not annoying every single person on the train. This time, the team set up a late night-style talk show, complete with desk, comfy chair, backdrop and band. Technically the band was just a guy with a keytar, but we'll allow it.

Black Friday brings out some of the most hilariously strange antics of us Americans. On Thanksgiving we give thanks for all the great stuff in our lives, and just hours later, we're waiting in massive lines and getting in spats with fellow consumers over the latest deals on video games. That's the good ol' USA for you.

The lighthearted pranksters at Improv Everywhere held their Third Annual Black Tie Beach affair over the weekend. Participants wore formal clothes and went to the beach, despite the fact that a soaking wet ballgown seems like a bit of a drowning hazard.

The creative folks at Improv Everywhere are great at pulling off pranks on a public scale. For their latest stunt, the troupe turned a mini-golf course into a major golf championship. Yes, they surprised random mini-golfers with caddies, ESPN commentators and a camera crew. The "winner" was even presented with the actual Claret Jug from The Open Championship!

Mac users used to live in fear of the "Spinning Beach Ball of Death," the twirling rainbow-colored circle that popped up onscreen when an application was not responding properly.

Improv Everywhere's latest trick is a short musical about mall Santas in which the singers emerge, one by one, out of the crowd of shoppers in a New Jersey mall. Check out the fun 'Mall Santa Musical' below.

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.

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.

On July 16, New York's Rockefeller Park was lit up like a Christmas tree when over 3,500 people converged for Improv Everywhere's latest MP3 Experiment. The popular series of "missions," as IE calls its stunts, asks participants to download an MP3 file, gather in one spot, hit play at the same time and follow the audio instructions for an awesome effect.
