let's not forget that "improvise" is the opposite of "practice until you get it right"

I saw a stultifyingly unimpressive improv show tonight, which reminded me just how bad improv really is.

I mean, if you go to a regular comedy club and someone isn't funny, you might sympathize with the comedian, or you might just dislike him. But when improv is bad, it's embarassing just to be there. I really just don't enjoy the bottom 99th percentile of celebrity impressions. It pains me, deep in my left ventricle.
