Dodgeball: A True Underdog Story
Peter La Fleur (Vince Vaughn) and his team of Average Joes defeat White Goodman (Ben Stiller) and his Globo Gym team in the Las Vegas Dodgeball finals. La Fleur does not get to keep his gym, because he signed it over to Goodman in exchange for $100,000, orignally believing his team would lose. Before the final match, La Fleur bets the 100 grand on his own team (they were 50-1 underdogs) and wins five million dollars, split between the six Average Joes team members. La Fleur, with his winnings, buys the majority of stock at Globo Gym, giving him control over the company. He converts it into a gym where everybody can be themselves.
