I forgot this in my earlier Hat PAD. This is that hat I wore at the 2000 Olympics in Atlanta. At the start, the had didn't have anything on it except the hatband. I saw people everywhere wearing and swapping Olympic pins of all kinds -- and I laughed at such silly people. Well, I bought one pin just for a souvenier -- and then another, and another, .... It became about obsessive as PADing. After several days, I got sort-of headaches that continued to get worse. Finally, someone pointed out that I probably had ten pounds of metal on my hat -- and dozens of pointy parts pressing down on my dull skull!
