Pick one or more of my userpics as shown here. Post a comment naming the pic by its keyword (or even hotlink it if you're feeling clever and html-skilly). In return I'll tell you where I got the picture, why I chose it, what it means to me and if there's any funny story behind it.
Disclaimer: there might not be a funny story behind it - in fact, in most cases there won't be, because how many people have funny stories about icons, for God's sake? - and the reason I chose it might be as simple as "I realised I hadn't got a picture of that character." If you're dissatisfied with my response, feel free to ask for another. :-)
