The video is from 94, back when people didn't understand that you had to practice fighting to be good at fighting. Truly this is only a few decades after people discovered that you had to exercise to be good at sports at all, so you can't really blame the guy for thinking that you just had to be big and strong to win a fight
Ever seen that pride of lions that tried to take out that giraffe and they just fucking... gave up after a while? Still think about that sometimes.
