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 peek
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

(Repeat)
