Dragon Ball Evolution Cartoon Network sweepstakes promo

Being a piece of Dragon Ball history widely forgotten, I remember prior to the release of Dragon Ball Evolution seeing a promo on Cartoon Network announcing a sweepstakes where the winner or winners could have a chance to win on attending the premiere of the movie. I remember Peter Cullen being the voice announcer as he done promos for CN around that time and I have seen the promo only once on Cartoon Network after-school possibly during a rerun of either Chowder, the Marvelous Misadventures of Flapjack, Total Drama Island, or Johnny Test. The reasons why the sweepstakes was widely forgotten was because it was rarely promoted and it might have been canceled because very few people have entered. Because I was very young at that time I might misremember it actually seeing it and it might not exist at all but I want to make sure if anyone remember about it
