In the Mental Health Institute, the director caught a client pulling up his shirt for a fellow inmate to lick his back incessantly. He asked:
– What are you two doing?
The other man retracted his tongue and replied:
– This is a newly invented game.
The director was surprised:
– A game? What are you two playing?
The other man explained:
– We are playing post office. This guy is the stamp, and I’m licking him to stick on the envelope.
