Currently all funny/awesome videos get posted in the shoutbox and lost after a few days, so here is a permanent thread I'm going to sticky which you will post all the videos you would post in the shoutbox. You can embed most videos using the 'Insert Video' button.
I'll start.

Touch Touch Your Gun
Snoop Dog/Kirby Remix (thanks Freddy)
TF2 vs Dr Weird (more in related videos)
