[lfjokes] In a mental institution ...

[simondo]

  In a mental institution, a nurse walks into a room and sees a patient
pretending as if he's driving a car, with his hands at 10 and 2. The
nurse asks him, "Charlie! What are you doing?" Charlie replied, "Can't
talk right now....I'm driving to  Chicago!"
 
  The nurse wishes him a good trip and leaves the room. The next day the
nurse enters Charlie's room just as he suddenly stops driving his
imaginary car and she asks, "Well Charlie, how you doing?"
 
  Charlie says, "I'm exhausted, I just got into Chicago and I need some
rest."
 
  "That's great," replied the nurse, "I'm glad you had a safe trip."
 
  The nurse leaves Charlie's room, and then goes across the hall into
another patients' room, and finds Ed sitting on his bed masturbating 
vigorously.  Very surprised she shouts, "Ed what are you doing!?"
 
  To which Ed replies, "Shhh, I'm screwing Charlie's wife, while he's in
Chicago"
