"I Saw Mommy Kissing Santa Claus" by Vonda Shepard

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.
