Yep, there is another one

[ginnyde]

Amy, a blonde Texas"city" girl, marries a rural 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 to the barn.

They walk along 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 dumb 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."
