The Humiliation Conga that Jyuza dealt to Raoh and his army. Outsmarting Raoh with a fighting style he literally just made up, stealing Raoh's horse and just to rub salt in the wounds, Jyuza slaps his own ass telling Raoh that he can "kiss his ass".
Kenshiro shoved one poor miniboss into a cannon, then shot it through a hot air balloon, then exploded when he landed (the scene is 9:10 minutes into the video). Speaking of that, Nanto Human Cannon technique does not look like it is a serious technique, but just some ridiculous child's trick playing the name of Nanto already.
Also, as mentioned in Crowning Moment of Awesome, Kenshiro blowing up the tank!
