I've seen quite a few people running around with one. It's by far the ugliest hat yet, but it's wat it stands for that matters.
Although to me it does seem like most people are just wearing it to boast, which isn't really what charity is about. I'd rather just donate a full $100 to a charity, no reduction because of taxes and no need for an ugly hat to boast to all the inferior people who don't have one.
hey, if some kid wants to spend 100 dollars in order to increase his epeen by a few inches, but in the process helps out a noble cause, that's win win in my view.
