I've got a few. The first one I didn't attend, this was recounted by a coworker.
A distant cousin (the groom) of her DH's was getting married 800 miles away, and called and asked if my friend's son (who the groom had never met) could be the ring bearer. My friend agreed, but wasn't thrilled with the idea of traveling 1600 miles to go to the wedding of people she hadn't met and her DH hadn't seen in ten or more years.
The bride and groom originally decided that all the men would jsut wear suits, so my friend went out and bought her six year old a suit. Two weeks before the wedding, the groom calls and says that the bride has changed her mind, that all men (including the ring bearer) needed to be in tuxes. Because the suit she had bought had been altered, she couldn't return it. So they get her son measured for a tux.
There had been several showers for the bride, and my friend had been invited to a couple of them. She sent a gift for one, regrets but no gift for the second. The brides mother complained to the grooms mother because my friend didn't send a gift to the second shower. The grooms mother than called my friends MIL who proceeded to admonish my friend for not sending a gift.
They left on a Thursday, friend and her DH taking vacation time and pulling the three kids from school to drive to the wedding. Spent all day and into the night on the road, only to arrive at the hotel and find out that the brides mother had cancelled their reservation and rebooked them into a place that cost four times as much!

(Don't ever allow someone else to make your reservation!!) The original place was now booked up.
The next day the grooms mother called them and invited them over to their house for a few hours--but made it clear that the house had been professionally cleaned earlier in the week, so the children would ahve to stay outside! They ended up going to the local theater and catching a matinee with the kids to keep them occupied before the rehearsal.
They get to the rehearsal at the appointed time, and all goes as planned, except that they made it clear that only the ring bearer was included in the rehearsal dinner--this is after the groom had told them they were all invited a few weeks earlier. Um yeah, the six year old is just gonna drive himself.

So they end up saying that it was going to be too late of a night and leave. Take the kids to Friday's or somepalce like that and then swimming at the hotel pool.
The next day they had to be at the church at 10:30 for an 11:30 wedding. NO idea why so early, they still haven't figured that out. They aren't familiar with the area, so leave a little extra time, and end up there almost 75 minutes before the wedding.
The wedding goes off without a hitch, son does great as the ring bearer. They hang out for the photo's then drive to the reception. Now it's about 1:00, and they were expecting lunch, right? Wrong. The reception food consisted of a few trays of cold appetizers (think cheese, crackers, and veggies), iced tea, and cake. There was nothing else to eat, and if you wanted anything to drink except iced tea you ahd to buy it from the cash bar. There were also about 30 chairs for 200 people, and no tables. They hand a DJ and dance floor though.
After two hours of standing around and trying to balance a tiny plate with some crackers and celery sticks, and three kids who at that point hadn't eaten since 8:00 am and it's 3:00 pm. So my friend tells her DH that they really need to leave and get the kids something to eat. The bride throws a hissy fit beacuse "NO ONE IN THE WEDDING PARTY CAN LEAVE BEFORE THE BRIDE!"
My friend packed up the kids and left, telling her husband that if didn't want to come with them, he could find his own way back to the hotel. He came. They stopped at the first McDonalds they came to and fed the kids.
I'll write out the other two later... they get better!
