A little old lady buys a pair of parrots, but cannot identify their sexes. She calls the shop, and the man there advises her to watch them carefully and all would become clear in time.She spends weeks staring at the cage and eventually catches them doing what comes naturally. To make sure she doesnt get them mixed up again, she cuts out a ring from a piece of cardboard and puts it round the male parrots neck.A while later, the local priest visits the old lady. The male parrot takes one look at the fathers collar, wolf whistles, and says, "I see she caught you at it, too."
