Got thinking about this because I saw this little preview of a Jim Henson Workshop project that's improv comedy + muppets. Love it. I don't know why I was surprised that these folks can make those puppets so expressive without rehearsing it over and over. Goodness, they're talented. In general, I just love improv comedy. It's not as funny as scripted comedy on paper... but, you know, it's not ON paper and knowing that makes it much more enjoyable. (I know: duh. I never said I had profound thoughts.)
Also, listening to My Brother, My Brother, and Me and I love it. I don't know if I'm the last person on the internet to hear about this (apparently it's pretty popular, but that could mean 50,000 listeners or 5mil). The interplay between these three real-life brothers is just incredible. You can tell they've been doing skits with and playing off each other for years and years. I've had to stop listening to this at work on my headphones because when I'm trying to suppress the giggles my coworkers probably think I'm either weeping or spasming.
