A farmer is giving his wife last-minute instructions before
heading to town to do some business.
"That fellow from Sematol will be along this afternoon to
inseminate one of the cows. I've hung a nail by the right stall
so's you know which one I want him to impregnate."
Satisfied that even his mentally challenged wife could
understand the instructions, the farmer left for town.
That afternoon, the "Inseminator" arrives, and the wife
dutifully takes him out to the barn and directly to the stall
with the nail.
"There's the nail so this is the cow right here." she tells
him.
"What's the nail for?" the guy asks.
Replies the wife, "I guess its to hang up your pants."
