Turk: Have you seen J.D.?
[meanwhile: J.D. is trapped in a water tower:]
J.D.: Where am I? Hello? Anyone?
[back:]
Janitor: No, I don't know where he is.
Janitor: [v.o.] Man, I love that adrenaline rush you get from lying to someone's face. Do it again.
Janitor: Dr. Kelso, I must say that your nose hair is not the least bit long and creepy like most old guys.
Dr. Kelso: Thank you.
