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."
