Killing the frog

The latest brief entails making a poster based on a page of text from Alan Fletcher's 'The Art of Looking Sideways'. My topic is Humour. A big field to plough, eh? Well, so far the only inspiration I've got is the quote about humour being like a frog, in that if you try and dissect it, you kill it. So look forward to images of frogs being hit with hammers, zapped in blenders and run over by steam rollers.
