Little Johnny was bored and he was bugging his mother, so she said, "Johnny, why don't you go across the street and watch the builders work? Maybe you will learn something. When he came home his mother asked; did you learn anything? Little Johnny replied, "Well, first you put the door up. Then the son of a bitch doesn't fit, so you have to take the cock sucker down. Then you have to take a cunt hair off each side and put the mothefucker back up." Johnny’s mother is shocked and says, "You wait till your dad comes home."
When Johnny's dad got home, Mom told him to ask Johnny what he learned across the street. Johnny repeated the whole story and his dad said, "Johnny, you go outside and get a switch.” Johnny replied, "Fuck you, that's the electricians job."
