Tomb, cost

Oh yeah, also, what should I dress up as for Halloween? It's a little harder to find a good costume when you know you're going to have to sit at a desk and wear it for 9-10 hours. I thought about using our TV cardboard box and making a tombstone, but whose name would I put on it? Not mine-that would be too weird. And also there's the whole having to sit in a box for 9-10 hours. Maybe I should cut air holes.
