Only do it if it's supposed to be part of the wedding. Otherwise, don't do it. It would be very disruptive and distracting and could make an otherwise beautiful moment very awkward. And it'd be something the bride and groom would have to remember for the rest of their lives every time they put on their rings.
Weddings have too much going on for anyone to keep track. It's not a concert. No one is checking for tickets. After the wedding, receptions have assigned seating. But by then, you'd be long gone and planning the next Tolkiened wedding.
Agreed that it's hilarious, but I'm pretty sure I've heard that if someone interrupts the portion, the officiater has to go through like.. a whole process legally because of it? I don't know if that matters realistically if he knows too and is cool though
