As retold by Bruce Lowitt

Mrs. Finkel walks into the kosher butcher to by some chickens.

"How much?" she asks.

"A dollar forty a pound," the butcher says.

"What! Elfman is selling them for a dollar thirty a pound."

"So go buy from Elfman."

"He's out of chickens today."

"Look, lady," the butcher says, "as soon as I run out of stewers, I'll sell them to you for fifty cents a pound. And you can't beat that price anywhere!"
