Well, my small contribution, a very old chestnut: Three elderly gents in the diner, the old Jewish waiter approaches to get the order. First elderly gent says, "I want tea, not too hot, no milk, no sugar." The second says, "I want tea, very hot, with a little milk and some sugar on the side." Third gent says, "I will also have tea, hot, and in a clean cup." Waiter returns with the tea, says, "Who wanted the clean cup?"
