True story:
About 20 years ago, when I was a youth in Vicksburg, I witnessed something that makes Gray's situation seem quite normal. My buddy played basketball for hours every afternoon, and one day, he asked me to go to an unfamiliar neighborhood to play with some other guys. The court was all dirt, and the backboard was plywood. Everyone there was about 2% body fat. I was too, but weighed in at about 120 soaking wet. I decided not to embarrass myself, and didn't participate.
This one guy was shirtless and had a belly button that protruded at least 2". I never had and have yet to see anything like it. I wasn't sure if it was his real name, but everyone called him Dick.
