 Jon Christensen had played many jokes on his friend Austin Brooks over the years. Now Austin, with the help of his wife and Jon s future wife pull the ultimate prank on Jon by blowing up his precious Lexus. But to make matters even crazier, the man responsible for the explosion is a back woods hick named Uncle Buck. Jon finds out eventually that under a lot of make-up from professional make-up artist Kevin Yagher (Face-Off, Leminy Snicket), Uncle Buck is really Austin Brooks!
