A recent favorite featuring the folk villain Pai Mei - which many of you will know from Kill Bill - as played here by Lo Lieh in Executioners From Shaolin (1977), a good example of what I call Crotch Fu. The evil priest's finishing move, used at least three times in the film, is as hilarious as it is nightmare-inducing. You can skip ahead to the 2-minute mark or watch the opening credits fight whole:
What is particularly epic is the sound design - divine choir for the grab, scream for the drag, comedy flute for the drop - which is used in every instance.
So now you know what to do when you get kicked in the nads. No need to thank me.
