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
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
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
