You're not gonna believe what I saw

I saw Mommy kissing Santa Claus
Underneath the mistletoe last night
She didn't hear 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 it with my own two eyes
Not only were they kissing
They were drinking milk and eating cookies together
Now I know how to keep a secret
'Cause I wanna stay on Santa's good side
You don't just tell everything you know, mhm

I saw Mommy kissing Santa Claus
Underneath the mistletoe last night
She didn't hear me creep
Down the stairs to have a peep
She thought that I was tucked up
In my bedroom fast asleep

But I wasn't

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

Don't you go telling her either
It's our secret
