This amazing breakdancer just blows my mind. His exploits were posted on PJ awhile back and it's a must see if you want to see what the human body is capable of. The no foot pushups are impressive but it's even more impressive when he does it with his back folded! Super-freaking-human.
There's a ton of other cool vids available on That Video Site with a very simple and convenient browsing system. If you must know I found the site while searching for Merv the Perv clips from SNL.
Edit: Found a neat breakdancing site -- STYLE2OUF
