Post amusing things that have happened to yourself. I'll start.
Being in high school, our history class took a field trip to the nearby Holocaust museum. Although I am Christian, I have a Jewish last name. Anyway, once we got to the museum, we were handed name tags so that the tour guide could call us by our actual names. I remember thinking to myself "Oh god, I know what's gonna happen. The guide's gonna see me last name, and I'm gonna end up being called on for like every question (Since the Jews were one of the biggest victims in the Holocaust). So the tour starts, and about 5 minutes through the tour guide starts asking the class questions. He asks for a volunteer, looks around, I see him glance at my name tag, and I get called on. This continues for the rest of the tour. In other words, my prediction was completely right.
