For their latest prank, NYC flashmob collective Improv Everywhere invaded Manhattan's 5th Avenue Gap store, wearing white morphsuits under their Gap clothes, and tried to blend in with the store's regular mannequins.

Improv Everywhere agents give a bunch of random kids the PGA experience by turning a regular mini-golf game into a full-fledged Open Championship, complete with caddies, commentators, and an honest-to-goodness Claret Jug.

Teaming up once again with their partners-in-pranking at the Guggenheim Museum, Improv Everywhere agents and volunteers hit a shopping center parking lot in Staten Island to take part in the troupe's latest mission: Car Alarm Symphony.

Improv Everywhere agents descend on Central Park to carry out their latest mission: Treat a random couple to a fancy dinner and private concert — all from the comfort of a park bench.

Best known for their annual No Pants Subway Ride, Improv Everywhere's latest mission featured "the worst ice skater ever" getting trapped in the rink as everyone else cleared the ice. Watch as he turns from novice to expert in minutes.

Using the 6 train of the New York City subway, Improv Everywhere staged the first scene of Star Wars: Episode IV - A New Hope. It's definitely an upgrade over their usually train station-clogging antics.

Remember when an anonymous genius divided the sidewalk on Fifth avenue into lanes for "tourists" and "New Yorkers?" Turns out it was Improv Everywhere—the same folks behind the annual No Pants Subway Ride. Click through for their video.

We were sporting our long johns all weekend, so we would have looked horrible at Improv Everywhere's annual No Pants Subway Ride. Luckily Gawker operative Stephen Kosloff was there to take pictures of all the panty raiders for our amusement.

The pranksters at Improv Everywhere have struck again: "For our latest mission, we installed a photography studio on a random subway car. We claimed that the MTA had hired us to take photos of every single person who rides the subway and that we'd be producing a yearbook at the end of the year. Most people were happy to pose for us, and the resulting photos show just how diverse New York subway riders can be." Bonus: They show just how gullible New Yorkers can be, too.

The merry pranksters from Improv Everywhere have posted their latest "mission" online. They set up an art gallery opening at the 23rd Street subway station, had tuxedoed waiters hand out drinks, recruited a cellist to perform, and put little signs next to the fixtures thereby "transforming them into works of art." Video of the group's antics is below.

The silly pranksters at Improv Everywhere just posted their latest stunt: The performance group sent 20 "agents" to JFK to welcome home total strangers with flowers and balloons, cribbing their names from car service signs. More photos and video of the shenanigans here. [Improv Everywhere]

It's true, as we reported this morning, that the the liberal prank group The Yes Men was behind today's spoof left-utopian Times. But there were so many more commie pinkos involved in the plot! The cabal sent out a press release tonight, revealing that their ranks include the Yes Men, protest group Code Pink (which disrupted the Republican National Convention and fought Marine Corps recruiting), Improv Everywhere (they did that tear-jerking little league thing), Anti Advertising Agency (the ad-sticker people) and a few others we're less familiar with. They want to make the headlines come true! So cute. After the jump, read the press release and find out which of their claims is being disputed by the Times.

Improv Everywhere just started a new blog, Urban Pranks, to document the many public stunts the group has inspired. The New York group famous for showing up at Best Buy in blue polos and freezing Grand Central has offshoots across the country that are doing things like a protest against protesting, a dinner party at Ikea, and a button in a park that says "Do Not Push" (when it was pushed, planted agents dance to "Everybody Dance Now" &mash; clip below). The blog does a great job quickly explaining each prank and then showing the money shot. And it's a sign of a much-needed rise in public silliness, which is just what young media types need.

Improv Everywhere is the cosmic balance to Gawker: a group of real-world performance artists who generally make people feel like the world is a magical place. And in this clip that's been making the rounds, they turn a little league baseball game into a major league match, with an NBC sportscaster, a Jumbotron, and I won't ruin the rest. See below.
