Jeremy and Isaac are out having a celebratory meal at Minky's Kosher Cafe. At the end of the meal, the waiter comes over and asks, "OK, gentlemen, will it be tea or coffee for you?"
"I'll have a glass lemon tea," replies Jeremy.
"Me too," says Isaac, "and make sure the glass is clean."
Five minutes later, the waiter returns with two lemon teas on his tray. As he's about to hand them out, he asks, "Who asked for the clean glass?"
