Nag-Nag-Nag

A farmer had a wife who nagged him unmercifully from morning till night(and sometimes later), she was always complaining about something. Theonly time he got any relief was when he was out plowing with his oldmule. He tried to plow a lot.
One day, when he was out plowing, his wife brought him lunch in the field.He drove the old mule into the shade, sat down on a stump, and began to eathis lunch. Immediately, his wife began haranguing him again. Complain,nag, nag; it just went on and on. All of a sudden, the old mule lashed outwith both hind feet; caught her smack in the back of the head. Killed herdead on the spot.
At the funeral several days later, the minister noticed something rather odd.When a woman mourner would approach the old farmer, he would listen for aminute, then nod his head in agreement; but when a man mourner approachedhim, he would listen for a minute, then shake his head in disagreement. Thiswas so consistent, the minister decided to ask the farmer about it.
So after the funeral, the minister spoke to the farmer, and asked him why henodded his head and agreed with the women, but always shook his head anddisagreed with all the men.
The farmer said: "Well, the women would come up and say something abouthow nice my wife looked, or how pretty her dress was, so I'd nod my head inagreement."
"And what about the men?" the minister asked.
"They wanted to know if the mule was for sale."
