A guy calls the company and orders their 5 day - 5kg weight loss program.

The next day, there's a knock on the door and standing before him a voluptuous, athletic, 19 year old babe from J.C. Dressed in nothing but a pair of Nike running shoes and a sign around her neck.

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 huffing and puffing, he finally gives up.

The same girl shows up the next four days and the same thing happens. On the fifth day, he weighs himself and is delighted to find he has lost 5kgs as promised.

He calls the company and orders their 5day - 10kg program.

The next day there's a knock at the door and standing before him is the most stunning, beautiful, sexy woman he has ever 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 despite his best efforts, 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 10kgs, as promised.

He decides to go for broke and calls the company to order their 7 day - 25kg 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're mine.'

He lost 31kgs that week...
