A biker is resting on an island. MisterJaw shocks him into leaving his bike. MisterJaw and Catfish fall into a gang of bikers, and they find riding to be the greatest challenge of all. MisterJaw jumps the Grand Canyon with the bike, and all the bikers praise him. He doesn't understand bikers' lingo, and he takes their praise as insults. This cartoon features lots of humorous motorcycle slang, and even a reference to Evil Knievel and his Grand Canyon jump.
