The Challenge: Sure, being a competitor on "The Amazing Race" comes with a lot of perks. World travel, the occasional bungee jump, quality time spent with someone you (theoretically) care about and Phil Keoghan. Then there are the challenges. Like the one home shopping hosts Brook and Claire faced. You remember, the one where Claire used a medieval catapult to hurl a watermelon at a suit of armor and i backfired straight into her in the face? Hard? We're still surprised she didn't die, much less finish the task. 

The Reward: A shot at $1 million. Which they didn't win. Not worth a watermelon fastball.
