More Xmas Carols
I Saw Mommy Kissing Santa Claus
I saw Mommy kissing Santa Claus
Underneath the mistletoe last night.
She didnt 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.
