Quote from Dr. Kelso in My Common Enemy
Dr. Cox: Dear God, she has an actual skip in her step. Dr. Kelso: Doesn't bother me as much as the whistling. Watch what happens. [The whistling proves to be contagious. A patient who passed Dr. Molly Clock and started whistling then passes Ted] Dr. Kelso: Why are you whistling, Ted? Your life is pathetic. Ted: Right.
