Yes, twice. I gave them each the best Bachelor Party they could have within their stated limitations. Within both of those different social groups, both parties were LEGEND.
I got each to the rehearsal and to the church on time. No taser was ever used. I may have wished that I had practiced the reception speech more, but if I fumbled, it only made them look better in their bride’s eyes.
One couple has been married happily 30 years now, but the other barely lasted 20 (and I still say that divorce was a mistake).
I did for my brother, but it was for a Mormon temple wedding. Only Mormons with a temple recommend are allowed in, and I was too young. He was 22 or so and I would be 18 or 19. I have no idea if he had any friends or not.
With Mormon weddings since the weddings are closed, they have a public reception for family, friends and church members. There is a line where people come by, shake everyone’s hands, say hello and then eat some mints and drink green punch.
Japanese weddings don’t have best men/maids of honor and there was a friend or two who may have asked me had we been in the States. Now at this age, the only role left with be as the father of the bride or groom, if I last that long and the kids get married early enough.
