I have a funny kind of related story. When I was 18 or 19, I used to work in a town that had an adult book store. One day, it put up a sign that said "ADULT ARCADE - NOW OPEN."
So I went with a pocket full of quarters expecting to see arcade games of an adult nature. I was saddened to find out that it was just a way for guys to hang out in a seedy back room watching porn videos for .25 per 120 seconds.
Needless to say, I was EXTREMELY disappointed. Every time I drive by an adult book store and see "ARCADE" I have to remind myself it's not the fun kind. I should probably mention I live in a VERY small farm town. We're quite naive here.
