Little Johnny's mom asked little Johnny if he had enjoyed the field trip. "Yes it was great - we saw sheep, horses, goats, and fuckers."

Mom: "er, fine, fine. I know what the sheep and the rest are, but what is a fucker?"

Johnny: "Oh, they're the animals that give us milk and steaks"

Mom: "but who said they were called, er, fuckers?"

Johnny: "that was our teacher. Well actually she called them "effers," but we all knew what she meant."
