The Weight Loss Program

A guy calls a company and orders their 5-day, 5lbs weight loss program. The next day, there's a knock on the door and there stands before him  a voluptuous, athletic, 19 year old woman dressed in nothing but a pair  of  running shoes and a sign around her neck. She introduces herself  as a representative of the weight loss company. The sign reads,  "If you can catch me, you can have me." Without a second thought, he takes off after her. A few miles later puffing  and puffing, he finally gives up. The same girl shows up for the next four  days and the same thing happens. On the fifth day, he weighs himself and  is delighted to find he has lost 5lbs as promised. He calls the company and orders their 5-day/10lbs program. The next day  there's a knock at the door and there stands the most stunning, beautiful,  sexy woman he has ever seen in his life. She is wearing nothing but running  shoes and a sign around her neck that reads, "If you catch me you can have me". Well, he's out the door after her like a shot. This girl is in excellent shape and  he does his best, but no such luck. So for the next four days, the same routine  happens with him gradually getting in better and better shape. Much to his delight on the fifth day when he weighs himself, he discovers that  he has lost another 10lbs as promised. He decides to go for broke and calls the  company to order the 7-day/25 lbs program." Are you sure?" asks the  representative on the phone. "This is our most rigorous program."  "Absolutely," he replies, "I haven't felt this good in years." The next day there's a knock at the door; and when he opens it he finds a huge  muscular guy standing there, wearing nothing but pink running shoes and a  sign around his neck that reads: "If I catch you, you are mine."
