I saw Mommy kissin' 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 kissin' Santa Claus last night
