Unless you're being cremated, blasted into space, or turned into a cyborg, everyone will need a coffin at some point in their life. (Usually near the end.) And a company called Casket Furniture figures that since you'll be spending thousands of dollars on your post-life home, you might as well enjoy it as much as possible.
So it will build you a custom coffin that's just as functional for when you're alive, as it is for when you're dead. Like its 'The Manhattan' model which is a completely playable pool table that's not just shaped like a coffin, it's actually a functioning casket. Of course, if you have no intentions of being buried in it, but still have a taste for the macabre, you can order one as just a "regular" pool table.
