I watched the Mash Report the other night, in the vain hope of some levity.

God knows why I keep going back. It's the same spirit of illogical optimism that keeps football fans turning up to watch a club in terminal decline.

I don't know what happened to comedy on the BBC. The manager of the satire squad has clearly lost the dressing room and the most ghastly clique has taken over.

The programme was practically all about Trump and Brexit. I wouldn't mind so much if they did quick punchy jokes. Set up, gag: set up, gag, that sort of thing. I was hoping they might surprise me with some revelation or insight I hadn't thought of.

But no. It was all speeches.

Nish Kumar sounded like a politics student getting uppity on cider in the union bar, reading out the clunkier passages of one of his essays.

There was many a beginning and middle to these stories, but seemingly no end. Mash, where is thy thing? I found myself being jolted out of slumber by the canned laughter machine, thinking: 'whoa, hang on! Did I just miss the punch line?'

There was a US guest who gave us her highly polarised view of US politics. Sadly, she got her polarities mixed up. She was obviously a student of the book of pantomime politics, because her whole polemic was based on this adaption from Animal Farm: Democrats good, Republicans baaad. Slavery was mentioned at lot. But her authority on this issue was undermined by the fact that she seemed to think Abraham Lincoln was a democrat. He was a republican. The man who shot Lincoln was a democrat, and the politician who reversed some of Lincoln's liberating legislation was a democrat. And the slave plantation owners were Democrats, not republicans.

These are basic errors for a UK moral grandstander - like the entire case of The Mash Report. But they are tragic flaws in a comic who has been flown over here to speak about her mastermind speciality!

It's bad enough when comedians bore us with their myopic politics. Even worse when they can't be accurate. Be funny, or be accurate, but don't be Mash.

In the interests of ticking the balance box on the diversity sheet, they did do one obligatory piece on Corbyn. One.

Which was so lame it actually put him in a good light. Yes, exactly. You're thinking what I'm thinking: profile managing of the subject of the sycophantic worship, Jem Cor Bin, was the aim.

There's a new style of joke that BBC comedy shows use when approaching the obligatory Corbyn gag:

It's known in the trade as Praise by Faint Damnation.

The 'joke' was that he's a bit boring because he's so nice. Yes, really. Nice. I'm not sure victims of the IRA and Hamas would have been laughing off the sofa at that one. Or the woman who was threatened with lynching by his mate from Momentum. (Whatever happened to those feminist principles you were touting, Mash reporters? You didn't seem to have any long term plans for those, did you?)

Meanwhile, whoever works the canned laughter machine deserves a BAFTA as the hardest working editor in showbusiness.
