A city boy was visiting the country and wanted to go hunting. 
The farmer lent the boy his gun, telling him not to kill any farm 
animals. 

The city boy headed off and soon after saw a goat. He 
managed to creep into range and finally shot it. Not knowing 
anything about animals, the boy didn't know what he'd killed 
so he ran to the farmhouse and described his kill to the farmer.

"It had two saggy tits, a beard, a hard head and it stunk like 
hell!" said the boy.

"Oh, shit!" said the farmer. "You've shot the wife!"
