Nasruddin had a bad-tempered goose that was always hissing and trying to bite him, so he took the goose to the market to sell.
As he handed the goose to the goose-broker, Nasruddin warned him, "This is a badly-behaved goose. Be careful!"
"Don't worry," the broker said. "I'll get you a good price."
The broker then began yelling, "Buy the best goose here! A fine goose! Good-natured goose! Buy the best goose here!"
Nasruddin snatched his goose back from the broker.
"I'm not selling this goose at any price!" he exclaimed. "I never knew what a good goose I had."
