I know this sounds like something AI would produce, but it's real:
Bride was fairly young (21-ish), had been raised by her father and grandmother after her mother died young, in a wealthy household. She was quite naive and inexperienced.
Groom was a "Mystery Man", 40-ish, and it was very vague how he made his money, but he seemed to have quite a bit of it. He was also "out of town" a lot on equally vague trips. Divorced. No mention of kids. No one knew much about him but the bride was head-over-heels in love. Her father wasn't happy about it but as she was of age, he went along with it.
The wedding was in a fancy hotel. Everyone was gathered for the pre-ceremony cocktail hour, when the groom (who was supposed to be bringing the minister) showed up, in a tux, unknown teenage son in tow, without the minister. There was some talking going on in the corner with the bride's family and Mystery Man.
The group went into another room for about 20 minutes, while people milled around whispering. Finally the father came out, made the announcement that there wasn't going to be a wedding, but please have more drinks and dinner would be served in a while for anyone who wanted to stay. He said he would explain later.
Some left and some stayed to find out what happened. It turned out that Mystery Man wasn't actually divorced yet. He came out later and was talking to people.
Here's where the real "fun" began. The bride's ex-boyfriend hadn't been invited but showed up anyway, quite drunk. He was behaving himself, though, so had been allowed to stay. He walked up to Mystery Man and held his hand out as if to shake hands. Instead, he cocked his arm back and punched the lights out of Mystery Man, who ended up unconscious on the floor. Ex-boyfriend was hustled away, cops were called and an ambulance carried off Mystery Man.
We had another drink and some more appetizers and left. She married someone else three years later.

Another one was the "shot-gun" wedding of my neighbor's daughter. After waiting almost an hour for the groom, he shows up sh!t-faced drunk with his parents. My neighbor was muttering about going back to his truck, getting his rifle and "shooting varmint". The wedding proceeded. I wasn't sure it was going to happen because the minister was on the verge of refusing to perform the marriage because of the groom's intoxication. Needless to say, the marriage didn't last long.

Another interesting one I only observed before the actual wedding but I can imagine the actual ceremony.
My niece was getting married at a chapel in Las Vegas, a very picturesque one in a cottonwood grove where a lot of celebrities got married. Very tasteful....especially for a Vegas wedding. You got your 15-20 minutes in the chapel and then it was out and the next party moved in. Being on a Saturday, the wedding parties were lined up through the parking lot, waiting their moment. There were "fancy" groups and everyday groups....and then there was the group behind us.
Bride looked like she was no more than 16, close to 9 months pregnant, in a very short white dress and a veil. Her mother never stopped sobbing and her father, who was wearing denim overalls and a flannel shirt, looked like he was about ready to explode. The groom, who didn't look much older than the bride. was dressed....well, let's say clad...in a tuxedo shirt that was worn completely open, showing off his flabby hairless chest. He had black cut-off shorts that had been hacked off unevenly and had strings hanging down, red-and-white striped knee socks and high-top black tennis shoes with no laces. He was wearing a black ballcap with the bill turned backwards. HIS mother was stony-faced and spent most of the time glaring at everyone.

If you want an afternoon of unbridled amusement, take a Saturday tour of wedding chapels in Vegas. The year before my niece's wedding, my sister and I went to Vegas to scout locations for the nuptials. We hired a taxi and gave him a list of chapels we wanted to visit. We'd run in, look around and grab info and then go to the next one.
One of them had a drive-thru wedding window. When we pulled into the parking lot, there was a wedding going on there. The bride (dressed in daisy-duke shorts, a shiny gold bikini top and a loooong veil) and the groom (dressed oh-so-elegantly in holey jeans and a black t-shirt that said "F**K YOU" in large letters on the back of the shirt and a cowboy hat) were sitting on the back of the convertible getting their hitchin' on. They then proceeded to attempt to perform what I assume most people do behind doors but the convertible moved and they almost fell off the back.
Oh, my niece's marriage didn't last, either.

I did go to one, but I don't know if you can consider it a "wedding" because the bride didn't show up. Cold feet.
