A creepy guy in my Chem Lab last semester asked one of my friends if I was from another country. He had seen my Munchen liscense plate, and being the dumbest person in the world, assumed that I was from Europe. I talked in German for the rest of the class.
Another time, I pulled my car onto the Quad lawn (the dorm I live in) and washed my car there. One douche-bag RA called the cops and when they came, they let me finish washing my car on the lawn. We talked about BMWs for an hour or so (being in hick-town, USA helps a little bit... BMWs don't exist out here) and after I was done, they told me that I had a nice car and drove away.
