Exquisite corpse #2 (Many thanks to Anon.!)

I saw the suspicious man turn around the corner with a potato in his hand. He entered the "Prancing Pony", a pub on the right-hand side of the narrow street, with his hat on. There was nothing particularly wrong with his porkpie hat apart from the odd combination of pigeon and peacock feathers pinned down at the front. He ordered a pint and paying no heed to the stuffed partridges posing on the wall, put his posterior down. The pub was empty but suddenly a pale-faced old woman came in, paused then approached him and said: "Password?" Putting his palm out, he produced the potato and said: "This is a pipe". Pleased, she took a peony out of her pinafore's pocket, a petal fell down so he picked it up, patted it and gulped it. With a puckered-up face, the woman said: "Pugh! Puff a bit at your pipe or you'll puff up Props Man!". He was indeed a privy prop person who had to put up with plain people on a permanent basis. "SO, what's this problem that's so pressing?" "I'd like to borrow a prop for a play, a pretended painting named 'Treachery of Images'. Please tell me what the price is?" "It's a twopence. The play is about pretence? Then perhaps you can borrow my porkpie pigeon-and-peacock-feathered hat, and the person underneath it." So the woman bought a pig in a poke and the props man took a part-time part in a play pretending, poker-faced, to be a painting on a partition-wall.
