Mulla Nasrudin went to see his lawyer about a divorce.
"What grounds do you think you have for a divorce?" the lawyer asked.
"It's my wife's manners," said the Mulla. "She has such bad table manners that she is disgracing the whole family."
"That's bad," the lawyer said. "How long have you been married?"
"Nine years," said the Mulla.
"If you have been able to put up with her table manners for nine years, I can't understand why you want a divorce now," the lawyer said.
"WELL," said Nasrudin, "I DIDN'T KNOW IT BEFORE. I JUST BOUGHT A BOOK OF ETIQUETTE THIS MORNING."
