If the many series of Have I Got News For You have taught us anything, it's that if a joke is topical, it doesn't actually have to be funny.
With that in mind, here's Labour's latest online campaigning masterstroke. A badly Photoshopped picture of the two senior Opposition politicians, mocked up to look like John and Edward off the X-Factor, slapped on a page on their website. No attempt to make a deeper political point; just a stupid joke. Childish, amateur, pathetic. But it made me smile. And now I'm writing about it here.
It's worked.
