Remember the story of Stone Soup?
A traveling beggar puts a big stone in a cauldron, adds well water, and hoodwinks the whole village into bringing vegetables and meat for a communal soup feast.
The beggar kept this scam going until one day, he woke up to find the cauldron missing.
He managed to scrape up cauldrons for the soup in the next few villages, but his luck ran out eventually.
“Okay, you don’t have a cauldron for soup,” he said. “We can make a big stone sandwich instead.”
Three cracked teeth later, angry villagers brained him with the stone.
