I try my jokes onstage. The only way to really find out if something is going to work is to try it on stage, and I try to be careful and bookend something new with a strong bit before and a strong bit afterwards. But it's fun to run on virgin snow. I like that feeling onstage of creating new footprints and not knowing what's going to happen.
