I remember he was a postman.I think he wore a hat with ear flaps. I also think he didn't have any lines. What you say about the play may be true but I think it was a lot funnier than Joan's film "Rabbit Test." She had a cameo as a nurse running in a hall shouting, "Hot bladder!" It lands up on the floor and she says something like, "So he'll wear a bag." No wonder she landed up dropping dead during surgery. Karma's a bitch, you know.
