The Prime Minister lost his rag during Prime Minister's Question Time in the Commons this afternoon.
He was in the middle of answering a question on the Government's proposed reforms of the Welfare Benefits system when he advised the House that he had "just about had it" with his testicles, which had been annoying him all day.
David Cameron explained that he had put on a new pair of pants that morning and he had been feeling extremely uncomfortable in the testicular area ever since.
"I doubt my wife Sam must have miscalculated when she bought this pair of trousers", the PM continued, "because there is no way these are a 34 waist. Unless, of course, my chuckies ballooned overnight. And I can't recall them doing such a thing, at least not since my first week as a fag at Eton."
Mr Cameron expects he will either have to return his faulty trousers to Saville Row or just wear an extra pair of underpants next Wednesday. If he does, he will be the first Prime Minister since Pitt the Elder to have entered the House sporting a double gusset.
I've heard of a Hung Parliament but this is taking things a bit too far, Mr Cameron!
