Horrible pumpkins

I used to spend quite a bit of time using knives, fake blood, etc, to create a terrifying pumpkin experience for trick-or-treaters. But this year I realized a much simpler method: carve a regular smiley pumpkin about 3 weeks prior to Halloween. By the time it rolls around, what you have is a semi-decomposed, blackened skin-looking pumpkin that looks like it may eat you or give you some sort of infection.
