COMEDY: Hooray! The annual SF Sketchfest is back. And it kicks things off tonight with Tim and Eric Awesome Show, Great Job!. Tim Heidecker and Eric Wareheim's titularly awesome show comes to town featuring a "fast-paced, live variety show, complete with short films, parodies, pranks and musical numbers." Special guests include Great Job! regulars David Liebe Hart and James Quall, and DJ Douggpound will perform an opening set. You can't miss this night of choice, absurd hilarity. You just can't.

NUDITY/FREE BOOZE: The FKK (Free Body Culture), an activist political action association, is having some sort of party where you can "drink some free booze of Trader Joe quality, be on a TV show, and put your John Hancock on a nude model," according to MyOpenBar.com. It sounds like you could also be indoctrinated into some sort of cult, so consider yourselves warned.
