Little Johnny’s mum asked little Johnny if he had enjoyed the school trip.”Yes it was great -we saw sheep, horses, goats, and fuckers.”
Mum: “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”
Mum: “But who said they were called, er, fuckers?”
Johnny: “That was our teacher. She called them ‘effers,’ but we all knew what she meant.”
