What would hurt more than having all of your skin removed? I don't think much would.
This pumpkin design seems to capture the pain and suffering of being flayed. It would certain give the neighborhood kids a fright. If I were to do one (and I probably will) I wouldn't hesitate to light it with a road flare. The creepy red glow would look great.
When I am not carving pumpkins, I run a bulletproof vest company. BulletSafe Bulletproof Vests are the value leader in body armor. We are very popular with people like armored car operators and ATM repairmen.
