Query: Funniest documentary ever made!

A documentary about a contest to win a hard body pick-up truck - you will laugh until you cry! The film follows the contestants from selection through the end of the contest when the last person still standing with a hand on the truck drives it away. You may think that you have nothing in common with the contestants but as each one gives up and limps away in defeat you will find yourself sad for them while cheering the others on. This is one you must see to believe and you'll want to see it again and again.
