I Saw Mommy Kissing Santa Claus

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 Clause last night!
