A blonde city girl marries a Cornish dairy farmer.
One morning, on his way out to check on the cows, he says to his wife ,“The insemination man is coming over to impregnate one of our cows today. I drove a nail into the rail above the cow’s stall in the barn. You show him where the cow is when he gets here, OK”
So the farmer leaves for the fields.
After a while the insemination man arrives and knocks on the front door.
She takes him down to the barn. They walk along the row of cows and when she sees the nail, she tells him, “This is the one…right here.”
Terribly impressed by what he seemed to think just might be another ditzy blonde, the man asks,
“Tell me lady, how did you know this is the cow to be inseminated?”
“That’s simple, by the nail over its stall”, she explains very confidently.
Then the man asks, “What’s the nail for?”
She turns and starts to walk away and with complete confidence, says over her shoulder, …
“I assume it’s to hang your trousers on.”’
