Amy, a blonde city girl, marries a Colorado rancher.
One morning on his way out, the rancher says to Amy, "The insemination man is coming over to impregnate one of our cows today. I drove a nail into the 2 by 4 just above the cow's stall in the barn. Just show him where the cow is, okay?"
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 the row of cows and when she sees the nail, she tells him, "This is the one."
The man, assuming he is dealing with an airhead blonde, asks, "Tell me lady, 'cause I'm dying to know; how would YOU know this is the cow to be bred?"
"That's simple. By the nail over its stall," Amy explains very confidently.
Laughing rudely at her, the man says, "And what, pray tell, is the nail for?"
"It's for you to hang your pants on."
