When I was little I was really bothered by the idea of seeing my mom kissing Santa Claus. I wondered why a mother would DO such a thing!
There is a parody version called I Saw Daddy Kissing Santa Claus. Other than The Dr. Demento Show, have heard it on the radio exactly once, many years ago. When the song ended, the DJ said "Okay folks, it's over. We won't play it again. Stop calling the station."
