"The Train Set"
Little Johnny was in the living room playing with his train set while his mother was in the kitchen getting dinner ready. Johnny would take his train around the track and stop then announce "all you mother fuckers getting on get on and all you mother fuckers getting off get off".
Johnny's mommy thought she heard johnny say these bad words but wasn't sure so she listened and sure enough she heard Johnny announce "all you mother fuckers getting off get off and all you mother fuckers getting on get on".
Johnny's mom rushed in the room and told Johnny that he was to go to his room and think about the language he was using and not to come down from his room till he figured it out.
So Johnny goes to his room and remains there for over an hour. Finally he comes down and tells his mother that he knows what he did wrong and it won't happen again. So Johnny's mommy says "ok go play and don't let me hear those words again".
So Johnny goes back to the living room and takes his train around the track and then stops it and exclaims "all you kind people getting off get off and all you kind people getting on get on and if you have any complaints about the delay talk to the bitch in the kitchen"
