I saw Mommy kissing Santa Claus
Underneath the mistletoe last night
She didnt 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※
(※くり返し)
Oh, what a laugh it would have been
If Daddy had only seen
Mommy kissing Santa Claus last night
