I first heard this song sung by Jimmy Dean, not the rebel without a cause, but the guy who used to flog sausages on TV. Another great version was Michael Cooney's (I'm not sure if it's available on record).

I used to teach music in public school and about 2 years ago I ran into one of my former students at a gig. She was all grown up with kids of her own, but she requested "that song about incest that you used to sing us in greade 4." I got her to listen carefully and she admitted that there was no incest in the song. I think only a public school secretary can fully understand it on first listening.
