Wow! Mommy's kissing Santa Claus! 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 He saw Mommy kissing Santa Claus I did! I really did see Mommy kissing Santa Claus And I'm gonna tell my Dad 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 Oh, what a laugh it would have been If Daddy had only seen Mommy kissing Santa Claus last night I did! I did! I really did see Mommy kissing Santa Claus You gotta believe me! You just gotta believe me!
