If people are going to do stuff like that, I don't think them changing the words of their vows is going to make them any more likely to stay together. Then again, I'd change that line in my vows to "Till yous a bitch."

Hey, we're all a bitch temporarily sometimes....
Here's my take on that (which I didn't even know was going on, but we're so far away from the pulse I don't even know where the arm is...):
Marriage is a contract. What you choose to put in your contract is none of my business. You get married where you like, when you like, by whomever you want, and it's not my concern. We got hitched in December years ago for the tax benefit (the timing, we were going to get married anyway), which (besides healthcare) is probably a key reason for some not-totally-gaga-for-each-other folks to get married these days anyway.
For my own experience, it won't likely end at death. We used to joke "The only way you're gettin' out of this marriage is in a body bag..." But now the hubby wants dibs on my soul too, should we be fortunate enough to get somewhere everlasting together. So for our marriage, it's not enough that we're here now together, we got the everlasting contract

And I'm happy with that. If one of us eats it first, the other will have to last here (sans-suicide) until their own bitter end, at which point we may be reunited. That's love, imho.
