I Saw Mommy Kissing Santa Claus - Christmas Lyrics

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
