Dragon Ball Kai - episode 83 - 27 Nov, 2010

When Krillin and Vegeta arrive, Trunks informs everyone of the tournament to be held by Cell and Android #16 asks to be taken back to Capsule Corporation where he can be repaired. Bulma also notifies everyone at Kami's Lookout to go there to meet up. After Cell finishes arranging his tournament, he then heads off to a news station to broadcast his message via television announcing details about his tournament, the "Cell Games," and states if that all the warriors lose to him, he will kill every single last human being. Meanwhile, Goku and Gohan are still training. (Source: Wikipedia)
