I think a hysterical moment to animate would be a scene from Mirror Shades. After Bomb Threat gets to The Maginot Nightsass is looking for nuts and fails the roll... The whole situation is pure gold.
Start at 13:00 - 15:10
This moment is mostly funny because of the banter outside of the game, so it may not be the best option if you're looking to keep the animation strictly motivated by the fiction.
