A girl had invented a device to cause any car that passed in front of
her house to suddenly break down, but couldn't find any practical way to
profit from it.

So, thinking clearly, she set up the device, and as the
cars passed the house and broke down, she'd offer the man in the car a
place to stay for the night.

Then as soon as the man was asleep, he'd be jarred awake by her with his
penis in her mouth, and she'd hold a sign up that said "$50 or I'll bite
hard!"

Of course, the guy would pay and she'd let him go.

Well one day, a Newfoundlander broke down, and had to stay the night.

Sure enough, he felt something between his legs at night, and there she
was with him in her mouth and holding the sign "$50 or I'll bite hard!"

The Newfoundlander just smiled and said "$100 or I'll pee!"
