Whenever something animated wins an award and the animated characters are shown making their acceptance speeches, do the companies producing them know the winner in advance, or do all studios actually animate acceptance speeches or what? The only examples I know of are at least two of the times when Rugrats won the "Best animated show" category at the Kids Choice Awards (1997 and 1998, I believe... Maybe more), and I think the first winner of the "Best animated feature" category at the Oscars.
Though now that I think about it, I think both times when Rugrats characters appeared to accept the award, I think the animation was all reused with new dialogue.
