I'm guessing this is from an early Poor Boyz film. JP Auclair skis down to the camera and says something like, 'Hi, I'm JP and today I'm going to teach you how to do a misty flip.' I saw this on a show once, and I'm pretty sure they were showing film clips.
On a related note, they also showed a clip of the guy who invented the screamin' semen. What's his name and has he gone the way of Josh Loubek and others?
