Expect the unexpected!!!The third season of Big Brother, the American reality TV show, aired 32 episodes during the summer of 2002, from July 10 to September 25.In this season, a new twist was added to the game, in that the HouseGuests could compete for a Power of Veto. At a weekly meeting, the winner could decide to veto a HouseGuest that the Head of Household had placed on the nomination block. In this season, it was not possible for a nominee to use the veto on themselves until the "Golden Power of Veto" was introduced.This was the first and only season to have every evicted HouseGuest vote for a winner. In Season 2, Justin was not allowed to do so, due to his expulsion from the game.
