A peasant was plowing, and a general rode by.
The general's horse had a stone in his hoof and was lame. "I need your horse!" yelled the general. "I order you to give me your horse!"
"Why should I obey you?" the peasant shouted back.
"Because I'm a general in the army!"
"I know what an army is!" said the peasant. "I was in the army. I got all my orders from the sergeant. You're not a sergeant!"
"I'm a general!" shouted the general.
"I don't know what a general is. Go get a sergeant, and I'll listen to him!"
