I did it, and it's easy.
1. Skin the head/face. Dig out the eyeballs.
2. Fire up the turkey roaster, fill with hot water to the brim.
3. Set the head down in the simmering water, careful to leave the antlers out of the water (they'll turn colors, if submerged.) I made a little wooden apparatus, that I tied the antlers onto, so just the skull was submerged.
4. Add a bottle of peroxide to the water, let simmer for 2-3 hours.
5. Keep pulling the head out, and skinning off the cartilage/nastiness that is cooked all over it. (you may want to change the water - b/c it will be NASTY with grease and stink).
6. Everything should come off quickly - if not, let it simmer more. Use a dull knife to aid - so as to not leave tool marks in the skull.
7. NEVER TELL YOUR WIFE THAT YOU USED THE TURKEY ROASTER FOR THIS EVENT - it will lead to certain death (and you springing for a new roaster at Wal-Mart).
8. I then covered mine in cotton cloth, and basted it with bleach for 3 hours in a pan of bleach (filled 1-2"deep)(the cotton will keep it wet).
9. Leave it in the garage to dry.
Getting the brains out of the spinal cord stem hole is tricky, I used a hose after boiling. I mashed it all up with a screwdriver and sprayed the hose in there. TIP - move your face while spraying. I got a facefull of cooked deerbrains.
Here's the finished product - not bad for a city slicker, eh?
