Zach Galifianakis Shows up on 'Law & Order' (VIDEO)

'Saturday Night Live' (Sat., 11:30PM ET on NBC) has been a bit lackluster lately, but Zach Galifianakis managed to bring some funny back into the show as host this week. In fact, he did that just by showing up.

In the digital short, Galifianakis showed up on various TV shows like 'Law & Order,' '30 Rock,' and 'The Dr. Oz Show.' He's probably been on a lot of others and we just haven't noticed him.
