My all time favorite Samurai episode was when Belushi 'met his match' with Richard Pryor.

I forget if it was samurai delicatessen or samurai hotel in-keeper, but Belushi did something really intense with his sword, looked at Pryor, and shouted out, 'yo mama-san!".

And then Pryor pulled out a sword and proceeded to wreck total havoc on the set, with more intensity than anything belushi ever did. In amazement, belushi/samurai looks at Pryor and says (for the first time in his normal voice), "OK, man, I can dig where you're coming from!" If you never saw it, just describing it doesn't do any justice, you'd have to see it.
