A man and woman got to a chinese restaraunt, The man calls the waiter over who is holding a tray with something on it and a towel over the top of it. Just as the Man is about to order he sees the towel move, and he see's an eye looking up from underneath then it tucks back under the towel. So he carries on, can I have ? Again the towel on the tray moves with an eye looking out, So the man asks the waiter what is that on the tray. Ah! that? says the waiter, Its just a peeking duck.
