Was totally worth the $110 or so.
It's a variety show so you get to watch him do what he did on "Who's line is it anyways", then you get to watch him sing and dance. I'm pretty hard to make laugh, but his comedy portion got me laughing. His singing/dancing portion, I didn't enjoy too much. Still by the time it ended, I felt it was easily worth the money.
As long as you don't pay for the VIP seats (~$170?) or volunteer, you won't be picked out from the audience despite what they at first so sit back and enjoy :)
