It all began with a dancing doodie. In 1998, brothers and JibJab co-founders Gregg and Evan Spiridellis saw a dancing turd (literally) in a video streaming over the Internet and it changed their lives forever. What they saw in their web browser was not just an incredibly amusing, dancing piece of dung, but also a once-in-a-lifetime opportunity to be pioneers in a brave new world of entertainment. And now, 8 years later, they've become a veritable Lewis and Clark (sans canoe).

JibJab has grown to become a premier online comedy studio, with literally hundreds of original productions to its credit, many of which involve some kind of fart joke. And if you tire of the dancing presidents, rapping forefathers and farting elves, check out the links below to send your friend a hilarious video greeting (Sendables), put yourself and friends into a video (Starring You) or visit JokeBox to see the funniest viral videos flying around the web!
