One morning, on his way out to check on the cows the rancher said to
Amy, "The AI 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 to 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 dizzy
blonde, the man asks, "Tell me little lady, how did you know this is the
cow to be bred?"
"That's simple. By the nail over its stall", Amy explains very confidently.
Then the man asks, "What's the nail for?"
She turns to walk away, and with complete confidence says, "I guess it's to hang your pants on."
