The women in my life, my mother and my wife, have repeatedly told me that people just do not get my sense of humor. What I find funny, others do not. Sometimes I hit the mark, other times I fail. I thought there were sufficient hints in the now-gone post to give away the joke: "Joseph K Simpson is my alter ego". It probably wasn't really funny in retrospect. What I was trying to do was find a way to reference a piece of writing I thought was pretty good (for me anyway) and when I found that photo of a man and his son at the beach with a boogie board (actually a wake board in the photo), I thought it went along perfectly with the story. Just a bit obtuse, I guess -- especially if you do not know my true identity.
Feel free to call me an asshole.
BTW, what if that was a an actual, two week old picture of the author of Fat in Indiana?
Let this be a lesson, never trust what you read on the internet.
