On the first day, a gorgeous cheerful big-titted 20 year old girl rings his doorbell. She is wearing nothing but a pair of running shoes and a sign that says, "If you catch me I'm yours." He chases her all week and loses 10 pounds.

The next week he asks for the 20 lb weight loss in five days program. An absolute stunner of a chick rings the doorbell, again, completely nude except for running shoes and a sign that says, if you catch me I'm yours. He loses 20 lbs that week.

Delighted w the whole thing, he calls the company and asks for the 50 lbs in one week program. They ask him, "are you sure--that's our most intense program?" He says yes.

So the next day, the doorbell rings and its a huge buff dude, naked except for some pink running shoes and a sign that says, "if I catch you, your ass is mine." That week he lost 63 lbs.
