Spenny used rollerblades, which are in fact a shoe.
17th Nov 2008 / Season 5 Episode 05
Both Kenny and Spenny wore various apparatuses on their feet to avoid touching the ground. The crew could not help the guys. Kenny got a bodybuilder to carry him up the stairs while Spenny was having trouble with his makeshift flowerpot shoes. Kenny used a wheelchair and a Segway to get around. Spenny planned to go out on a friend's boat after Kenny had fallen asleep. Spenny declared that touching the floor on a boat in the water would not count as being on the ground. Spenny waited in a harness chair, but while he was waiting, Kenny knocked away his flowerpot shoes and anything else Spenny could use to walk on by using a basketball (the rules stated that neither person could touch the other guy's stuff), leaving him stranded in the harness. Kenny tormented Spenny in the style of a James Bond villain, shooting him with pellets, tennis balls and pennies, throwing live crabs at him, and placing an electric eel in a pool under the harness. While taunting Spenny, however, Kenny lost control of his Segway and fell off.
Endurance competitions entail lasting longer than the other guy. They include competitions when the other guy might get caught or break a rule first, as they didn't endure longer.
