In episode 12A (Doug and the Yard of Doom) of season 3, Doug, Skeeter, and Patty are playing with a new Frisbee type toy in the beginning of the episode. Suddenly, Patty's father comes to pick her up "for Judo". Then you see Patty's father in the car, which Patty promptly enters, and the car speeds off. Now why is this weird you ask? Because Patty's father, Chad Mayonnaise, is a paraplegic. It is revealed in episode 2 of season 3 (Doug rocks the house) that Patty's mother is deceased and that her father gets around on a wheelchair, which basically means hes paralyzed from the waist down. If that is indeed the case, how the hell is he driving?!
