If you liked Sesame Street as a kid and enjoy twisted humor you have to go see Avenue Q the next time you're in New York. My eyes were watering through most of the show I was laughing so hard!
My favorite part of the musical? I'd have to say the musical number “The Internet Is For Porn”.

Recommendation: Aim for third to fifth row center... too far back and you can't see well, too close and you can't see the TVs (which show the occasional animated bit).
