Vive La Revolution!
The time is the French Revolution. Yossi lives in a small village and one day, his friend Jacques comes to see him after returning from a trip to Paris. Yossi asks Jacques what's happening in Paris as he has heard that they are regularly using the guillotine.
"Yes you heard right," says Jacques. "They are chopping off people's heads by the thousands."
"Oy vay," moans Yossi. "What's going to be with my hat business?"
