And now the parody, transcribed from the sound file at The Record Lady's All-Time Country Favorites, Country Christmas page:

I SAW MOMMY SMOOCHIN' SANTA CLAUS
(as sung by Homer and Jethro)

I saw Mommy smoochin' Santy Claus
Underneath the Christmas tree last night.
She puckered up her lips.
Pleasure she was a-seekin'.
She missed his mouth and kissed his nose
And the doggone thing was a-leakin'.

Then I hear'd Mommy tell old Santy Claus,
"Santy you have got to change your way.
Go and get yourself a shave.
Then I will be your slave.
Kissin' you is just like smoochin' Gabby Hayes."

I saw Mommy smoochin' Santy Claus
Underneath the Christmas tree last night.
Their smoochin' was so loud
It woke up Uncle Fudd
It sounded like a cow a-pullin'
Her foot out of the mud.

Then I shot Santy with a B-B gun
And you should have hear'd old Santy squall;
Then he jumped about ten feet
And he took off up the street
And he hollered, "Merry Christmas to you all!"
