Weddings are supposedly solemn and serious affairs but there are times when accidents happen. The good thing is that no one gets really hurt, physically. I guess only the egos end up bruised. Funny things that could happen in a wedding can be a result of a variety of things. For instance, the bride or groom could be so nervous or the guests are very much intoxicated and having lots of fun.
In any case, the funny bits in a wedding are the ones most remembered. They will be played every family occasion and each time, that person will relive his embarrassment.
