Story : Host John Henson will undoubtedly be laughing just a bit louder in this episode since he's the brains behind of one of its featured obstacles. About his creation he proclaims: "As an inventor, one hopes to create something that changes the course of mankind -- the wheel, the steam engine, the bedazzler. Today I am proud to present... the TRAMP-O-MEAN. Your move, Stephen Hawking." Diving Board Shape Shifter and Double Cross with Fire Hose are also among the new, wild and outrageous obstacles included in this week's episode of "Wipeout," featuring the world's largest obstacle course.
