Nurse: Happy birthday, Dr. Kelso.
Dr. Kelso: Oh, thank you.
Elliot: Oh, my God, is that a smile?
Dr. Kelso: Well, it's like the last year, when the safety brake failed on Enid's wheelchair, and she started rolling toward our pool, I told myself: "Bob, it's already too late to stop it so you might as well sit back and enjoy it."
