The Guardian almost had me going with this piece about Gordon Brown's upcoming election campaign:
Following months of allegations about Brown's explosive outbursts and bullying, Downing Street will seize the initiative this week with a national billboard campaign portraying him as "a sort of Dirty Harry figure", in the words of a senior aide. One poster shows a glowering Brown alongside the caption "Step outside, posh boy," while another asks "Do you want some of this?"
Brown aides had worried that his reputation for volatility might torpedo Labour's hopes of re-election, but recent internal polls suggest that, on the contrary, stories of Brown's testosterone-fuelled eruptions have been almost entirely responsible for a recent recovery in the party's popularity.
Unfortunately, it got silly enough after that to ruin the joke. But those two paragraphs actually sounded disturbingly plausible.
