I took lots of photos at my son's wedding. It wasn't until months later, when I was loading the SD card onto my computer, that I noticed that I had accidentally captured one of their college-aged friends leaning over a table and showing quite a nice nip-slip while at the reception.
I have no idea who she is or what exactly she was doing, but I'm sure that alcohol added to her carelessness, which allowed the wardrobe malfunction.
