I Saw Mommy Kissing Santa Claus

I saw mommy kissing santa clause,
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 clause,
Underneath his beard so snowy white,
Oh what a laugh it would have been,
If daddy had only seen, mommy kissing santa clause last night.
