Cameron's clangers: the jokes the PM may regret In January 2012, he angered disability campaigners by comparing working with Ed Balls in the House of Commons to "having someone with Tourette's sitting opposite you?" At the time, one critic noted: "For lots of people, Cameron's casual use of a disability to insult another politician will be shocking." In September 2011, he was accused of humiliating MP Nadine Dorries, labelling her "frustrated" in an apparently unintentional double-entrende. In an exchange at PMQs, Dorries asked: "Is it time the Prime Minister told the Deputy Prime Minister who's boss?" To jeers and laugher from the chamber, Cameron replied: "I know the honourable lady is extremely frustrated...about...err... maybe I should start that again. I'm going to give up on this one. In January 2012, he was accused of ageism after calling veteran Labour MP Dennis Skinner a "dinosaur" after he asked a question on the Leveson Inquiry. "It's good to see the honourable gentleman on such good form," he said. I often say to my children, no need to go to the Natural History museum to see a dinosaur, come to the House of Commons at about half past 12. In April 2012, he repeated the sentiments, telling Mr Skinner he should take his pension in reply to a question about Culture Secretary Jeremy Hunt's employment rights. Cameron said: "The honourable gentleman has the opportunity at any time to take his pension and I advise him to do so." In March 2009, he told the Commons Gordon Brown wore so much make-up on television that he "resembled Barbara Cartland." In October 2011, Cameron called Ed Miliband a "complete mug" during a heated debate relating to the European Union in the Commons. In Novemer 2010, he used a lunchtime speech to journalists to ridicule Speaker John Bercow, musing on how he might behave at the Royal wedding and suggested he might interrupt the ceremony to say:"Order! I want to hear what the Prince is saying! He also used the opportunity to relate an anecdote in which junior health minister Simon Burns's driver reversed into the Speaker's car in a Parliament courtyard. Cameron described Mr Bercow told Mr Burns: "I'm not happy!" To which Mr Burns replied: "Well, which one [of the seven dwarves] are you?" In 2009, he compared Peter Mandelson to an extra-terrestrial, telling a member of the public in Tynemouth, North Tyneside: "I'm convinced we have been visited by alien life forms - and one of them is the Trade Secretary Peter Mandelson." In June 2011, he crudely inferred he had given "pleasure" to Conservative MP Peter Bones" wife, in an exchange relating to the Greek bail-out. Mr Bone had sought assurances from Cameron on behalf of his wife ,that the UK would not be required to participate in a bail-out before 2013, saying that "she would be very happy if he could give her that undertaking." To roars of laughter, Mr Cameron replied: "I do feel now that a very big part of my life is trying to give pleasure to Mrs Bone. I feel on this occasion I can only go so far. In May 2012, he called Ed Balls a "muttering idiot" during an argument about the economy. The Speaker John Bercow intervened to ask Mr Cameron to withdraw the word "idiot" which he said was "unparliamentary."
