The Unfaithful Wife

Morris returns from a long business trip and finds out that his wife has been unfaithful during his time away.
"Who was it?" he yells. "That shmuck Goldstein?"
"No," replied his wife. "It wasn't Goldstein."
"Was it Feldman, that dirty old man?"
"No, not him."
"Aha! Then it must have been that idiot Rabinovich!"
"No, it wasn't Rabinovich either..."
Morris was now fuming. "What's the matter?" he cried. "None of my friends are good enough for you?"
