Weddings are one of society's most traditional practices, with many formalities carried over from the days when things were done a little bit differently. As a result, even though weddings are still fun and memorable events, little antiquated details remain, and occasionally cause chaos. 

“Should anyone present know of any reason that this couple should not be joined in holy matrimony, speak now or forever hold your peace.” It's a line right before the bride and groom are pronounced husband and wife, and was originally included to make sure someone had time to check if the marriage was legal. (Back then people had a tendency to hitch up with their relatives, or people who weren't of age.) 

In modern marriages, anybody with an objection usually has plenty of time to air their grievances before the couple winds up at the altar, but disgruntled relatives still use "speak now" as an opportunity to make someone else's big moment all about them. No marriage should have to deal with a public objector, and anyone with a shred of social awareness knows the question is very much a rhetorical one. Unfortunately, that didn't stop the people at these 20 holy matrimonies from trying.
