It was only two years ago (at age 18!) that I finally understood that in the song "I Saw Mommy Kissing Santa Claus" the father had dressed up as Santa Claus and 'mommy' was kissing her husband. It had always perplexed me as to why mommy would want to kiss Santa Claus. I still feel pretty dim whenever I hear that song.
