Zach Galifianakis is a funny dude. And really, that's all it takes to make an episode of Saturday Night Live great, instead of just "meh."

The Hangover star kicked the night off strong with his monologue, and continued steadily through the night with a Scared Straight sketch, a spoof of The Talk and a digital short where he looked for an assistant.

And there was, of course, the requisite Charlie Sheen joke. Bill Hader adjusted his impression in order to reach crazy town levels, much like Sheen has done since last week's SNL.

What did you think of Zach's hosting performance?
