Keir Starmer walked out of a pharmacy, having just collected his prescription, as he walks back to his car, the (obviously Jewish) owner of the pharmacy bursts out of the door and chases after him looking flustered. "Oi vey, Sir Keir, there has been a terrible mistake. We have a trainee on today, a dyslexic, he should have dispensed Cyanocobalamin but he picked up the wrong box and gave you Cyanide!" Starmer stopped in his tracks and replied, "Oh dear, that doesn't sound good. But Cyanocobalamin, Cyanide, what's the difference?" The pharmacist quickly answered "£7.50!"
