Went to see Colin & Brad from Whose Line Is It Anyway at our local venue. Hilarious!!! Tears were rolling down my face several times. It amazes me how quick they are with the improv act. On the funny videos thread, there's a post with their mousetrap act, and they did the same sorta thing here, too. If you have a chance to see it, I definitely recommend it.
They grabbed several people from the audience to do bits or throw out suggestions for stuff. There was obviously one groupie there. He had mousetraps attached all over himself. You'll have a great time, for sure.
