I had actually never seen a standup act live, but my sister got me tickets to see Chris Kattan playing host for Finesse Mitchell and Jeff Richards, and it was actually hilarious. Kattan sucks though, even with all the SNL and improv stuff in his career he's only been doing standup for like 3 months or something and he fell really flat. How that dude has been coasting on an effeminate voice for this long is a real mystery.
Norm MacDonald's coming through next month though so I'm super stoked for that, dude is the fucking best. His appearance on one of the Comedy Central roasts a little while back had me in physical pain with laughter.
