I find the second one hard to believe...people sat there for almost 5 hours waiting for the priest & minister to finish debating?
Wow! I didn't realize this one got pulled up for "review"--I'm honored!

The second story of the marathon-dueling-men-o'-God is mine. And yes, Mbbored, it's absolutely true that we all sat there like lumps, mouths dropped open. I think it was a combination of not wanting to be rude by getting up and leaving in the midst of what was still a wedding and (likely mostly) like seeing a wreck--you can't really believe what you see and you can't really look away.
ETA: After seeing some of the other questions, I'll answer as best I may. Please bear in mind that when this took place, I was a kid still living at home. I'm far from a kid now.

1. We were in our seats at about 11am. When we left, it was getting on for 4pm.
2. People may well have been sneaking out the back. If they were, they were very, very quiet about it, other than folks taking out crying babies and/or screaming small children. And had I turned in my seat to look, Mum would've clouted me 'round the ear-hole.
3. My biggest memories of the day was a) how hungry I was getting and b) how very, very badly I needed a bathroom. We did not go on to the reception; we stopped at a restaurant because of Mum and Dad also suffering from a) and b) above and we were all just tired at that point. Next time we visited the Grandparents, Mum mentioned the wedding and Grandma just held up her hand "stop" fashion. Since the entire family consisted of my Dad, his Mum (Grandma), his step-father (Grandpa) and his half-brother (Uncle), and me (Great-aunt and Uncle were unable to attend due to health and both my brothers were in the Army by then), we didn't have anyone to compare notes with.
4. Yes, the attendants stood through this whole thing. How, I dunno, but based on what little I'd seen of my (at that point) aunt-to-be and what little I saw of her afterwards, I would guess fear of what she might do if someone fainted on *her day* may have entered into it. That is strictly my hypothesis based on my impressions of her.
