I think Paul should do a skit like the carpool thing in which or during which he walks up and asks strangers for their autograph. Yeah, man, that would be cool.
Even cooler, and this will NEVER happen, imagine watching a show and when the commercials on, you just catch Paul in the background. One half of a second. He's playing the guitar in a commercial, a commercial for veggies, skin cream, whatever, and bingo, WTF? That would be sweet. It's cheeky. That's cool.
