I am all for a quick and cheap pumpkin gag and this is one of my favorites. Using black twizzlers for dreadlocks is going to be the new thing in town. Be the first of your friends to do it. I suggest using a drill to make the holes for the twizzlers to go into.
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.
