Dug!! What a fowl trick to play on Penfold! It's best to stop egging him on. Give him a breast and he'll take a wing. Much more than that and you don't have a leg to stand on.
Could be both, considering he used one of my photo's in his book.
The chicken polishing, btw, was a thing that cropped up at the Convention when Marc Burrows and Rob Wilkins were on stage together and it just stuck. There's even a Facebook Group "Chicken Polishers" that was created within a couple of hours and I suspect it will become a 'thing' at future conventions, like many of the spontaneous 'traditions' have become.
