     A man calls a company and orders their 5-day/10-pound weight loss program. The next day, there's a knock

on the door and there stands before him a voluptuous (艳丽的), athletic, 19-year-old girl dressed in nothing but

a pair of Nike 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 out of breath, 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 10 pounds as

promised.

     He calls the company and orders their 5-day/20-pound program.

     The next day there's a knock at the door and there stands the most stunning (漂亮的) and beautiful woman

he has never seen in his life. She is wearing nothing but Reebok 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 20 pounds

as promised.

     He decides to go for broke (全力以赴) and calls the company to order the 7-day/50-pound 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!!!"

He lost 63 pounds that week.
