Willy's rolling down the hall of a retirement home acting like he's driving a car, an orderly turns the corner and asks Willy what he's doing.
Willy replies, "I'm going to Chicago for the weekend."
The orderly chuckles and enters Bob's room to check on him. He catchs Bob pleasuring himself, when asked what he is doing, Bob replies,"I'm screwing Willy's old lady while he's away in Chicago."
