I seem to recall (though I can't find it now) once writing something about a Twitter feed which regularly posts spoof Jeremy Corbyn jokes - the punchline always 'demonstrating' Jez's relentless far-left earnestness and complete lack of a well-functioning sense of humour.
As so often these days the real thing often beats the parody.
Today saw Jez.we.can being asked the famous Mumsnet question, "What's your favourite biscuit?", and, quick as a flash, in all seriousness, he replied:
I'm totally anti-sugar on health grounds, so eat very few biscuits. But if forced to accept one, it's always a pleasure to have a shortbread.
As funny as @corbynjokes can be, they'll never surpass that.
