As a kid whose first exposure to Pat Morita was The Karate Kid, I remember the first time I heard him talking on an interview, I was like, "Damn, Mr. Miyagi's English has really improved." No, there's no point or punchline.
At first I thought he was referring to "nipple" (he did grab his man boob). I thought that was pretty racy for the time. I then realized what he really meant.
