Don't forget the tax breaks. That's why the gays want marriage rights so bad.

I think seldom is it that your wife and your best friend are the same person. Too many things you can do with one and not the other. Unless you get real lucky and find the girl who somehow likes to watch hockey, go fishing, play video games, and still be able to raise your kids, cook, clean, and stay slim, it just isn't very likely. So happily if you do get a wish fulfilled by killing your best friend, you most likely will still have your wife around. Unless she narcs you out, the skank.
