Focus Features

In case you weren't aware of the crazy, wacky and very funny Zach Galifianakis, the good folks at Videogum have put together a compilation of some of his greatest comic moments, in anticipation of the release of his latest film, It's Kind of a Funny Story (which Focus Features are releasing October 8). 

Check it out below. If I have to pick one, my favorite is his appearance in Kanye West's video for "Can't Tell Me Nothing," in which he and Will Oldham (aka "Bonnie" Prince Billy) hang out on Zach's farm.
