In a mental hospital, a nurse walks into a room and sees a patient acting like he's driving a car. The nurse asks him, "Mark, what are you doing?" Mark replied, "Vroom,wroom, I am driving my Mustang to Chicago!" The nurse wishes him a good trip and leaves the room. The next day the nurse enters Mark's room just as he stops driving his imaginary car and asks, "Well Mark, how are you doing?" Mark says, "I just got into Chicago." "Great," replied the nurse. The nurse leaves Mark's room and goes across the hall into Randy's room, and finds Randy sitting on his bed furiously jacking. I mean, the guy is beating his meat like it owes him money. Shocked, she asks, "Randy, what are you doing?" Randy says, "I'm screwing Mark's wife while he's in Chicago!"
