You really have to watch this video which I saw featured on Iain Dale's blog. I recall once telling a Labour Assembly Member, who intervened during one of my speeches to make some mindblowingly boring and irrelevant party point that he was the 'Eric Joyce of Welsh politics'. Not everyone in the debating chamber understood how deliberately offensive I was being. Watch this clip and you'll realise that its not possible to be more rude. The Presiding Officer really should have ruled such an insult out of order.
