I saw mommy kissing santa claus, Underneath the mistletoe last night, She didn't see me creep down the stair to have a peek, She thought that i was tuck 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 have only seen, Mommy kissing santa claus last night, I saw mommy kissing santa claus, Underneath the mistletoe last night, She didn't see me creep down the stair to have a peek, She thought that i was tuck up in my bedroom fast asleep, And 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.
