A ride at the top of the Stratosphere Tower in Las Vegas which lives up to its name. It hangs you over the edge of the tower and spins you around and around, and the seats, due to centrifugal force, tilt downward so you're facing the street roughly 1000 feet below while spinning. Not recommended for the weak stomached, for their sake as well as the people walking on the Strip down below.
Next time I make it out to Vegas I'm riding the Insanity. The other rides up there are cool and all, but this one looks just insane.

The definition of insanity, is, doing the exact same fucking thing over and over again, expecting shit to change. That. Is. Crazy.

Trying to solve problems,
Expecting different results,
Using the exact same methods...

3) A type of behaviour where a person may act in a way that may be seen as "uncool" or "weird" (and doesn't care).
3) The only way to fly.
