Here's a kung fu movie that everyone should see. It's terrible but funny/entertaining at the same time. I rented it when I was 18 and still remember it to this day.
One guy has his arms chopped off (even though one of his arms looks like a baby arm) and the other has his legs burned with acid. Anyways, the guy with legs wears him like a backpack and they fight like that. It's hilariously sad.
