OK, I haven't read the whole thread but "I was there reading Chat Rifles joke" years back, while one or two had just posted their responses, and I got it immediately and laughed loads. It's counter intuitive. I don't understand why it's been such a slow burner. A few 'wtf' comments made it better but I dunno... if said in the pub by the right person it would have made immediate sense, especially in a Radio 4 voice.
