I Saw Mommy

So, we have begun listening to Christmas music in the car.
"I Saw Mommy Kissing Santa Claus" came on. Alek listened for awhile and then said, "This is a really weird song. I mean, why would anybody even think of this? I don't think you would be kissing any man like that."


I really had no way of responding to this in any detail. Suggestions anyone?
