Since we are sharing stories...my then-girlfriend's work friend scheduled a wedding on Lake Winnipesaukee in late October in 2007 -- coinciding with game 3 of the World Series. My gf didn't care about sports, and was annoyed that this frustrated me. But the wedding was scheduled for 1pm, and the game was starting at 8pm...so this wasn't going to really be a problem. Go to the ceremony, hit up cocktail hour, watch the intros and the first dance, eat dinner, GTFO, home in Boston by first pitch.
The invitation had not made it clear that the lovely couple had scheduled a four hour break between the ceremony and the cocktail hour. So guests could explore the Lake area, their favorite place in the world. In late October. When it was 40 degrees and pouring rain. The wedding party didn't enter the reception until almost 7:30pm. The real audacity was the husband and wife entering to Dirty Water -- because they are such big fans of Boston!
I rotated up to the big lounge and bar on the second floor and watched some of the first part of the game, but obviously not enough. My gf got super drunk and we left "early" (being about 9:30pm, after a 1pm ceremony). She spent the car ride complaining that I cared more about people I will never meet than actual people in our actual lives. She and I stayed together for almost nine years; we never spent one more minute with the couple who got married again.
