Oh, Adrian, I've been thinking about this for a good two years now - knew the concept and couldn't, couldn't, couldn't remember what it was called or how to find out. I kept hopefully googling 'bowler hat insult'; and I'm not quite sure why I thought that was going to help.

Now I need no longer ponder. Really, thank you. Font of much (some? occasional? No, I'll go with much) wisdom, this blog.
