In a major change of pace from his work in The Hangover, actor and comedian Zach Galifianakis is working as the executive producer for a new documentary called Craigslist Joe. The movie is about Joe Garner, who traveled across America living off Craigslist ads.

Over 31 days, Garner sought transportation, food, and shelter through ads on the online classifieds network. All he took with him on the journey was a laptop, cell phone, toothbrush, and the clothes he wore. Get a first look at the movie with the trailer above. The movie is slated to hit theaters and iTunes on August 2.

Craigslist has been at the center of many weird and wacky stories. Strange things wind up for sale on the network, from a 1/3-size scale model of a Star Wars TIE Fighter to a human skull. Although you can search directly for something you need, browsing the Best of Craigslist can also just yield some laughs.
