A woman goes to the pet store and wants
buy a special parrot. Pet shop owner: "Take this one, the one with the two strings on the legs." Woman: "What happens if you pull on it?" Pet shop owner: “Try it out.” The woman pulls on a string, the parrot lifts its leg and says: "Hello. Hello." The woman is excited and pulls the other string, and the parrot lifts its leg again and says, "Good evening. Good evening." The woman is fascinated and thinks out loud: "What will happen if I pull on both at the same time?" Then the parrot said: "Then it'll hit me in the face, you stupid cow!"
