One night Billy went to pick up Lisa for their first date. When he arrived Lisa was not ready yet. So, Billy sat down on the couch in the living room with Lisa’s parents to wait.
Along comes the family dog, Rufus, and lies down at his feet. Billy waits and waits. All of the sudden he has to fart. He can't hold it back, so he lets out a little one.
The mother says, "Rufus!" in a scolding tone.
"Phew," thinks Billy, "they thought it was the dog!"
A moment later, Billy has to fart again. He figures he can let it go a little louder, but still doesn't want to press his luck. So, he lets it go.
"Rufus!" says the father in a scolding manner.
"Phew," thought Billy, "they still think it's the stupid dog!"
So as Billy waits for Lisa impatiently, he realizes he has to fart once more. He figures he doesn't have to hold it back at all this time since the dog is getting blamed. So, Billy lets another one go!
The mother screams, "Rufus get the hell away from that boy, before he shits on you!"
