I just remembered this one; it happened about 6 years ago. I was at a friend's wedding really early. My wife and I were supposed to be setting up a video camera and stuff, when the bride poked her head out of a room and asked us for help.
My wife went in and the bride said, "no, I need both of you," so I went in, too.
She was mostly in her dress, everything was covered, but she couldn't get the buttons herself in the back, of course. My wife was like, "Don't you have a personal attendant or bridesmaids here to help?" She said that they were ALL late, every single one of them. Even the bride's mother was late because she was stuck until the other late people could give her a ride (the whole wedding was a disaster, by the way).
As my wife was trying to button the buttons, the bride was freaking out about a loose thread that she spotted across her chest. She told me to find where it was coming from and rip it off. I told her it looked like it was going down the front of her dress so maybe my wife should get it.
The bride said, "I don't have the patience to care for your prudishness right now--just get it out," so I pretended to be careful, but I looked down the front of her dress and saw her tiny breasts and really tiny areolas and nipples. I then discovered that the thread was just loose and probably from a scarf she had on earlier. I told her I didn't actually see anything when I was looking around, and she totally believed me.
My wife said, "That was the weirdest 10 minutes of my life," and I agreed. I never told her what I saw, and frankly I forgot about it, but it's kind of a funny story that was the last thing I would have expected.
It was fun seeing her during the wedding and knowing what was under her dress.
