I didn't make that up, BTW; I don't mean the actual pig bit obviously, but its narration as it came to my late wife -- all as I got it from Valerie, who got it from her much-loved old neighbour whom she called 'Uncle', Ivor Hopkins. He would tell her also that when he had misbehaved as a child, his father would thrash him, saying as he did so, "I've been in prison, my bwoy, and I'll larn thee to stay out!"
