Ok, so a couple of weeks ago, I stopped at a head shop, looked around and saw that they were selling those buttons that are all the rage these days. I looked at the impressive collection and I saw one that read 'Hung Like A Donkey'. Needless to say, I bought it, haha. Mostly as a joke, however. The question I have is this: should I pin it to my backpack? Is that too pretentious to do? I already have a couple pinned to it ('Bert is Evil', 'Kill your television', stuff like that) but not something as bold as this... What would you think of someone that had a button like that?
