Apple Trebek

Apple Trebek is a character who only appears in Fruit for All. He is the host of the game show Fruit For All, in which Orange was a contestant on in the episode, playing against a banana and a pineapple. Orange's obnoxious behavior landed him in last place, far behind the other two contestants. However, the Final Fruit question which would decide the winner ("Table, bread, and butterfly are all types of what?") was answered correctly by Orange (his answer was, "Knife"), however, Apple was sliced in half by Knife. Apple was then struck by lightning, soon after Orange was grateful that the final round "wasn't the lightning round".
