Well the same thing could happen again. I'm imagining that it wasn't particularly pleasant the first time, and just because it (probably) can't get worse, doesn't mean the same outcome won't hurt less. So it seems that one thing he has to lose is some amount of happiness (at least in the short term).
That being said, go get 'em, it probably won't happen again :)
