A TV show on ABC where Contestants compete on what is billed as "the
world'
s largest obstacle course". Obstacles change from season to season, but the trademark obstacle, the "Big Balls", remains. Contestants must
try to cross four large red balls without falling off. Though this task is practically impossible, a few contestants have successfully crossed them. Other elements often seen include the "Sucker
Punch", the "Sweeper Arm", and the "Dreadmill".
