An elderly man, Willy, mimes driving a car as runs around the halls of a retirement home.
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."
