Sad Videos for Silly Games

[D-Class 198482]

I recently stumbled on a video for TF2 called 'What happens when your team loses'. It was fairly sad, and that got me thinking: what other sad videos for some silly games are out there?
Post away, either describe or place the videos on this thread.

The music for the Game Over screen of Donkey Kong Country used to depress me.
