A severely obese man, upon the advise of his physician,
goes into a quick weight loss center.
"First time?" asks the receptionist. "We’ll start you out on the 10
pound program."
She takes him into a room and departs, locking the door behind her.
In the middle of the room is a nude woman with a sign on her:
"IF YOU CATCH ME YOU CAN FUCK ME"
He chases the attractive woman around the room for an hour or so
until catching her and doesn’t come out for another hour or so.
When he finally gets home and weighs himself, he’s lost twelve
pounds.
Needless to say, he loves this place. He returns the next day with
his fifty bucks handy. "I’ll try the 20 pound program today." She
takes him to another room and locks him in just as before. In the
middle of the room is a 400 pound gorilla with a sign on him:
"IF I CATCH YOU I GET TO FUCK YOU."
