Road Kill Man is a man who got run over, and now resembles a raccoon pancake you see on the side of the road. He appears as the postal worker in the Netherworld and is seen when the Maitland's go to see Juno. Being as he's a postal worker, he (like the receptionist, Miss Argentina) probably committed suicide- jumping in front of a truck or car of some kind. It's not direct about his death, however. He wears a suit- though it has some pretty gnarly tire tracks across the front.
Oddly nice fellow. Likes to tell jokes and seems to enjoy his new line of work. Heh. Getit? LINE of work? Man, I really crack myself up sometimes, I tell ya. kee'oth rama pancake!
