Animaniacs - Season 1 Episode 10 -

Michelangelo paints the ceiling of the Sistine Chapel. He must finish before the pope arrives and prays for assistance. Assistance arrives in the form of the Warners who first paint the ceiling completely white and then fill it with pictures of Elvis and dogs playing poker. Michelangelo convinces them to help him make the correct painting and they agree. They, however, add an interesting touch before the pope arrives.
