When I was down in San Diego County a few weeks back some kid went to Cirque du Soleil and exposed everyone there to Measles, which resulted in two dozen more infections.
Apparently it was some rich kid who'd just gotten back from a ski trip in Switzerland and his mommy considered him too good for immunizations. Hey, it was La Jolla, after all.

Anyway, I've always wanted to see it, but everytime they've come around, or I've come around them, it hasn't been in the cards.
