C5     C5   A5     E5 
I saw Mommy kissing Santa Claus 
A5     C5        A5    C5         G5 
Underneath the mistletoe last night. 
    D5     D5    G5 
She didn't see me creep 
         C5     C5   C5 
Down the stairs to have a peep; 
     D5          A5     D5 
She thought that I was tucked 
   D5     G5       D5     G5 
Up in my bedroom fast asleep. 
      C5     C5   A5     E5 
Then, I saw Mommy tickle Santa Claus 
C5  C5     C5    C5    F5 
Underneath his beard so snowy white; 
            F5       D5        G5 
Oh, what a laugh it would have been 
   C5      E5       A5 
If Daddy had only seen 
D5     C5      A5     F5     G5   C5 
Mommy kissing Santa Claus last night.
