A friend of mine built a coffin in college (he's a woodworker), so tombstone works just as well. You can pre-order anything, really. He used it for Halloween, but I'm sure he still has it kicking around.
I love how the very first comment on the article blows it almost entirely away. Somebody threw that article together for a deadline without actually looking into the facts or relevance of most of the points made.
Doesn't look like he could stop until he reached the end. Liked the bridge part.
