As the doctor aboard a plane in which the pilots, and some of the passengers, become violently ill, Nielsen says they must get to a hospital right away.
"A hospital? What is it?" a flight attendant asks, inquiring about the illness.
"It's a big building with patients, but that's not important right now," Nielsen deadpans.
When he asks a passenger if he can fly the plane, the man replies, "Surely you can't be serious."
Nielsen responds: "I am serious, and don't call me Shirley."
