Even in these gloomy days, all it takes to lift yourself out of wage slavery and become unhealthily rich is one bright idea.

Bestselling authors and entrepreneurs Benrik are overflowing with cutting-edge schemes that they simply don't have time to develop themselves.

Includes:

* Celebrity-worn underwear: fans would pay a premium to purchase underwear actually worn by their favourite stars, however fleetingly.

* A chain of beginners' gyms: Where beginners can exercise without fear of ridicule (and with fake weights).

* Airport Public X-Ray Machine: Manufacture giant screen x-ray machines, so the bored queuing travellers can assist with explosives-detection.
