Suicide by Roller Coaster.

The three-minute ride involves a long, slow, climb — nearly a third of a mile long — that lifts one up to a height of more than 1,600 feet, followed by a massive fall and seven strategically sized and placed loops. The final descent and series of loops take all of one minute. But the gravitational force — 10 Gs — from the spinning loops at 223 miles per hour in that single minute is lethal.

I think the idea should be expanded to include bumper cars wired with C4, Willy Wonka style elevators that shoot up into space, and clowns that just walk around with shotguns. Oh, and one in every ten corndogs is laced with ricin.
