We wanted to do something on coffee for a long time, but just couldn't crack it – one of those cartoons that sulked around for ages as a provisional memo: "Something weird or funny drawn in to the froth of a coffee, like they do with cappuccinos or Guiness." We've got a pile of those, ideas that, you know, are great and so nearly there, but just need that little extra icing on the cake ie the joke, for God's sake. All part of the delusional process – like thinking going to bed in your tracksuit will make you fit. PW
