[Knowledge Bot]

i really want to learn how to do these. its been bothering me since i played the first one. its not in the trick book and i heard their possible and that people do them all the time. ( 10 points for the best and quickest response) thanks BTW its a video game for 360, if you can tell how to do them in real life then thats kool too.
