Gavitron

Properly known as "The Gavitron", The Gavitron is a man bestowed with great powers of seduction and intrigue. His quick rise to fame was predicted by few, and admired by most. Always the star of the party, show, or scene; All the ladies want him, only the best can have him.

The Gavitron meets an Australian Girl:

Gavitron: Pleased to meet you, I'm The Gavitron.
Girl: Gavitron? Isn't that a carnival ride? I've ridden that before.
Gavitron: No. You're thinking about the GRavitron. But If you ever want to ride The Gavitron, Just let me know.

Later that night, She did.

gravitron

A gravitron is the ride at those crappy city to city carnivals that spins real fast. It smells of vomit and sweat and features weight lifting benches on rollers along the wall. Your back is placed upon the bench with you in a semi standing position and the gravitron is activated. Once it reaches speed the benches slide up giving you the feeling of weightlessness. In actuality it is more the centrifugal/centripedal force that allows you to "stick" to the wall.

This guy i work with plans to buy a gravitron and travel the country as a carnie, but we were looking on usedrides.com and they're like $40,000 used!
