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
