Turk: Whoa!
J.D.: None of them showed up. I got us all these glow-in-the-dark necklaces so we wouldn't lose each other when we were out on the town.
Turk: It's their first day of med school. Come on. You remember how we were.

J.D.: Nerds!
Turk: Losers! [bicycle bell tinkles]
J.D.: I feel so alive.
[present:]
Turk: Everybody at that party had sex.
