Season 2: Episode 26

Jonesy gets a job in the mall's spa. Meanwhile, Jude tries to compete against his rival Mike Dent in a skateboarding race. He starts to practice by pulling Caitlin around on his skateboard, but when he finds out he's getting slower, he goes to great lengths (such as shaving all his hair off) to go faster. Little does he know that the only reason he's getting slower is because Caitlin is gaining weight at her part-time job, where she eats nothing but free chocolate.
