Turning the JZ into a nop to fallthrough to the next line is easier, right? That might be what he did in the quickfix area anyway. The self-marriage part was pretty hilarious. "Do I take myself? I do!"

Of course, it isn't legally recognised anywhere. And I doubt it will be – marriage as a legal relationship between two distinct people has various legal consequences on property law, taxation law, etc – a self-married person is legally indistinguishable from an unmarried person. But no law against holding a party called a "self-marriage ceremony", if your guests are happy to attend it.
