Arnold came up with a great party idea a few months ago: we'd each make a list of our favorite YouTube videos and then watch'em at a party. My friend Lisa added "let's make pizza" and thus a wonderous new tradition was born. On Saturday we gasped at parkour videos, giggled at Captain Jack Sparrow and rapped along with Jimmy Fallon and Justin Timberlake. It was ridiculous fun. Also? There was pizza. Lots and lots of pizza!
