I've been to a few events at Upright Citizens Brigade Theatre, and each time I've left happy. The gang specializes in improv comedy, and now they're giving fans everywhere a chance to participate. A new online show called HP ePrint Live makes improv an interactive experience by bringing YouTube, UCB and HP together.

Here's how it works: You send in ideas for an improv sketch, and it's e-mailed to a printer on stage. Comedian Rob Riggle and members of the UCB will respond to the e-mails in hilarious, spontaneous ways.
