The story behind the writing of the Wedding Arrggh was actually pretty much out there - dashed if I can remember much of it though. I'm fairly sure that Steph is right and there was a connection to the comic book wedding emerging around the same time.
And...something to do with them wanting to make them married for real all along, the clone having come in
after the ceremony and there's a scene in one of the later post-arrrghh episodes that still exists from that notion which wasn't edited out, some line or two of dialogue which only makes sense if they were married at the time...
....sorry, my memory on it all is so hazy. But I'm sure it'll be documented somewhere. Zoomway's website perhaps? Or perhaps in old threads on Zoomway's mbs - if you could track them down. Or, I'm sure that some of the old timers would still remember over there if they were asked.
