Little Johnny was in the toilets at school having a piss. Another boy entered the toilets and also started to piss. The other boy said, "Hey Johnny, your dick is bigger than mine!" "That's nothing," replied Johnny, "My dad has got two dicks! "The other boy replies, "That's not possible!" But little Johnny says it is and that he has seen them. The other boy asks, "Oh yeah, what did they look like then?" "One is small and wrinkly and he uses it for weeing," answered Johnny, "And the other is long and stiff and he uses that to brush mummy's teeth!"
