Blonde Texan City Girl

A Blonde Texan city girl, marries a Texas rancher.

One morning, on his way out to check on the cows the rancher says to Amy, "The
artificial-insemination man is coming over to impregnate one of our
cows today. I drove a nail into the two-by-four just above the cow's stall
in the barn. You show him where the cow is when he gets here, okay?"
So the rancher leaves for the fields.

After a while, the artificial-insemination man arrives and knocks on the
front door. Amy takes him down the barn. They walk along a long 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 little lady, how did you know this

She turns to walk away, and with complete confidence, says, "I guess
