Double Dragon 2
I remember when we originally bought this game for NES and my brother and I played it. We called that knee-attack (the one that makes the enemies fly pretty far) "Knee-oh". One Saturday morning (3am) he decided to jump around the house pretending to do that attack screaming "KNEE-OH! KNEE-OH!" for about 14 hours straight.
The next morning, he somehow managed to "Sleep walk" outside and lock himself out.
Excellent animation. I was actually wondering a week ago or so if there were any Double Dragon movies here on Newgrounds. Now I know there is at least one and it's a good one. (Thanks for not showing them climb those ladders ;))
