Often I write stuff here and, as I click ‘Publish’, I think, “Is that really funny or am I just deluding myself? Has sitting alone here in my pyjamas reading the news on the Web sent me a bit mad?” Perhaps my cackling at the absurdity of life, politics, and everything is in fact a symptom of some chemical imbalance in my brain. Today I recalibrated my sense of humour by examining what passes for funny on the Liberal Democrat Website. I am a comedy genius.
