I heard this first in Puerta Vallarta, Mexico, in 1969 (or was it early '70? Banned in a lot of places). My travel pal was having an affair with the hotel tennis coach. That didn't last (surprise) but he did move later to the LA area and was friends with a bunch of us, bright guy. Back in '69, he put the record on the sound system of the hotel..
We all cracked up (not many guests that day, and maybe not a boss or maybe the boss liked it or maybe he was the boss that hour).
