Here's the poster Labour released midway through last night's debate to accompany Gordon Brown's claim that David Cameron favours "a big society at home, but Little Britain abroad".
Brown's soundbite may have been obviously rehearsed but it was still one of the most effective lines of the night. Most voters won't have watched the full debate last night, so the soundbites that got picked up by the news bulletins mattered more than usual.
Brown's line has the added virtue of being true. Cameron's Europhobia and his High Tory scepticism of America have left Tory foreign policy without any obvious anchor.
But I'm not sure about this poster. ConservativeHome  has ludicrously claimed that it mocks the disabled (have they seen Little Britain?) but it's actually just not very good.
As you can see, the Tories' rapid-reaction unit released their own Little Britain poster in response.
It continues Cameron's assault on Labour's misleading leaflets. But to echo the Tory leader's attack on Nick Clegg last night, Cameron shouldn't put himself on a pedestal.
In other words, Dave should put his own house in order first.
