So this was a weird one, with lots of little things happening, but nothing really huge. It's all about people losing the things that make them special, voluntarily or involuntarily. Puck loses his mohawk when his dermatologist has to shave his head to examine a mole. With the mohawk goes his mojo. So he decides to get it back by dating the school's most popular girl -- Mercedes.
She's not interested until he woos her with a smoking rendition of "Lady is a Tramp." They date until he gets his cool back, at which time she dumps him for being a jerk. But not before she goes toe-to-toe with a very pissed off Santana in a face-off both musical and physical.
