A little boy comes running in to his mother and says, "Johnny just Shit all over the dog.'
The mother, in shock, says: "Didn't I tell you not to curse young man, and what do you mean Johnny pooped all over the dog, explain yourself."
The little boy says, "Yes mommy Johnny pooped all over the dogs head. He held the dog down, then pooped on his head!"
The mother still in shock says, "Why did Johnny do that?"
The little boy says, "Well the dog humped Johnny's leg and wouldn't let go, so Johnny said he was gonna teach that dog a lesson."
The mother asks, "Did Johnny tell you what that lesson was?"
The little boy says, "This will teach him not to fuck with Johnny!"
