If you know what a skateboard is, you should know who Rodney Mullen is. Here's why.
It's videos like this that made me think I should buy a skateboard and learn to ollie. Another dream unfulfilled.
Also, any gamer (and only gamers) should get a kick out of this unbelievable (literally, I still refuse to believe it) Quake III rocket jumping video, and as every other link to this video also states, ignore the boring intro. Once you get to the parts where they are showing the footage from a 3rd person perspective, you can't stop watching.
Whenever I would try to rocket jump, I'd always just blow up.
