The only version I know is to O, Tannenbaum.

"To thee we sing, to thee we drool, National Embalming School.
We stuff the corpse; we stuff the ghoul, Nat. Emb. Sch.
    *If you feel hollow deep inside
    We fill you with formaldehyde.
Our boys get hot ere you get cool, Nat. Emb. Sch."

There's another verse I don't remember, except the * section:
..."And when you die, we dig a hole
      And put you in to turn to mould"...

Get that education. George Bush insists.    Tw
