Lyrics:

Wow! Mommy's kissing Santa Claus!
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

He saw Mommy kissing Santa Claus
I did! I really did see Mommy kissing Santa Claus
And I'm gonna tell my Dad

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

Oh, what a laugh it would have been
If Daddy had only seen
Mommy kissing Santa Claus last night

I did! I did! I really did see Mommy kissing Santa Claus
You gotta believe me! You just gotta believe me!
Come on, fellas, believe me! You just gotta believe me!
