[Intro: Chorus]
Oooh, oooh

[Verse 1: Jimmy Boyd]
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

[Verse 2: Jimmy Boyd & Chorus]
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
[Outro: Chorus]
Ooh-ooh-ooh-ooh-ooh
