I Saw My Parents Kissing Santa Claus lyrics

I saw daddy kissing Santa Claus Underneath the mistletoe Last night He didn't see me creep down the stairs to have a peek [Mike screams "Oh GOD!"] He thought I was up in the bedroom fast asleep Then, I saw mommy kissing Santa Claus Underneath the Christmas tree last night there must be some mistake was I really awake? I move in closer, but better look away (Mike and Billie make barfing noises)
