Cirque du Soleil - I wish I had gone to see this show last time it was in New York, I figured I'd catch them next time around, not realizing that wouldn't be for several years. Now I have to wait till 2001, however, I was lucky enough this new years eve 2000 to be at a tv that had cable and see some of their shows on the Bravo channel. This is a circus with no animals, it's all people in funky freaky colorful leotard costumes doing varous acrobatics and contortionism, and no it never gets boring, not for a second.
