There was a receptionist at this place I was working at in Cleveland. She was a temp and very hot. Anyway, she ALWAYS wore a thong, or at least that's what I like to imagine. We could always see her from a distance but she couldn't see us -- anyway, one day, I suppose her thong was slipping so she reached around to her back, grabbed the thong, and pulled it up. All with one hand.
It's really quite an extraordinary sight to see something like that. One one hand, it's thong sexy, but on the other, it's like, "huh, I suppose wearing a thong is a bit like giving yourself a wedgy".
