From Kelp the Great:
This is the entire "A Fistful of Yen" clip from the 1977 film, The Kentucky Fried Movie. This clip is the longest and (in my opinion) best part of the entire film. As I could not find just this clip to watch online anywhere, I decided to upload it myself. I used the Freemake Video Converter program to edit the film down to just this clip.
A Fistful of Yen is almost a shot-for-shot parody of the Bruce Lee film Enter the Dragon. I'd rate it PG for slapstick violence and some crude humor.
In case you're confused by the sudden entrance of the bodybuilder, he's a cameo character from another clip from the full film. His inclusion is just to be silly, you don't need to see the rest of the film.
