One time in Paris I was going out at night wearing a long wrap dress and walked over one of those air vents in the sidewalk... luckily I caught my dress in time!
The really funny thing was that my mom and I had gone shopping for a dress for me to wear that evening, and the dress I *almost* went with was a version of the one that Marilyn Monroe had worn in The Seven Year Itch. That would have been pretty funny.
