Another Weekend At The Home
Willy, a mental patient, mimes driving a car as he runs around the halls of an asylum. 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 another patient's room and catches Bob pleasuring himself.
When asked what he is doing, Bob replies, "I'm screwing Willy's old lady while he's away in Chicago."
