I Saw Mommy Kissing Santa Claus - Christmas Carols

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
