16. I did a blackface Halloween costume one year. A black pirate. I did such a good job on makeup...
...that several people, including a few real black people, were fooled at first.
The most interesting thing that happened, however, was when I walked up to a bar where I was a frequent customer. The bartender, who had served me beer dozens of times and knew me personally, didn't notice me until I spoke up - "What does a man have to do to get a beer around here?"
She was pretty embarrassed. I felt like I had been invisible.
