In little Johnny's class at school there was a kid with no arms or legs, called Matthew. One day after school, Johnny goes round his house and knocks on the door. Matthews mother answers the door and says, "Yes Johnny, what can I do for you?"
"Can Matthew come out," asked Johnny, "We are all skipping in the park."
Matthews mother says, "But Johnny, you know he has no arms or legs."
"Yeah I know," says little Johnny, "I just want to see his stumps bleed!"
