On TV tonight
Grey's Anatomy, 9 p.m., ABC After Owen called Cristina a baby killer two weeks ago, the show decides to take a week off and be a little more light-hearted. That's right, it's one of these shows: "What would the cast be like if they played the opposite of their character?" Those are always fun.
24 Hour Catwalk, 10 p.m., Lifetime The designers have to turn a chenille bathrobe into a catwalk-worthy garment ASAP. Don't worry, that's considered high fashion at our house already.
Unsupervised, 10:30 p.m., FX Gary and Joel become managers of the high school baseball team in order to remain positive. Obviously they don't remember anything about high school. Or baseball.
SERIES PREMIERE I Just Want My Pants Back, 11 p.m., MTV Some Brooklynite in his 20s runs around the city looking for the girl with whom he had a one-night stand. Easy, dude: Just go out with another girl and you'll run into her by accident. Happens every time.
