Bob Bolton, regarding your 09:40 PM 25 Nov 02 post of this parody:

Santa Claus is dead -
They found him in a toy shop;
A bullet through his head.
A note pinned to his jacket,
Confirmed what papers tell:
That he was on the payroll
Of Toltoys and Mattel.
-snip-

Here's two children's rhymes that are similar:

Jingle Bells {Version #3}
{to the tune jingle bells}
Dashing through the snow
on a pair of broken skis
over the hills we go
crashing into trees
{bam bam bam}
the snow is turning red
I think I might be dead
Oh no! I'm in the hospital
with needles in my head
Jingle bells jingle bells
Santa is dead
because Rudolph took a 22
and shot him in the head
Oh, Barbie girl barbie girl
tried to save his life.
But Ken from Mexico
stabbed her with a knife.
-Alexandra, age 13 years {Canada}; collected by Azizi Powell; 10/24/2005

Jingle bells, jingle bells, Santa's lying dead.
Teletubbies Teletubbies stabbed him in his head.
Barbie girl, Barbie girl tried to save his life.
Action Man, Action Man stabbed him wi' a knife ...

There may not be any connection between these two rhymes and the one you posted years ago. At the very least, they are all part of the "Santa Claus is dead" parody family.
