I saw Mommy kissing Santa Claus, Underneath the mistletoe last night. She didn't see me creep Down the stairs to have a peep, She thought that I was tucked up In my bedroom fast asleep. Then, I saw Mommy tickle Santa Claus Underneath his beard so snowy white, Oh, what a laugh it would have been, If Daddy had only seen, Mommy kissing Santa Claus last night.
