so I drove a nail into the 2 by 4 just above where the cow's stall is, in the barn.

Please show him where the cow is when he gets here, OK?'

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

Amy sees the nail, she tells him, 'This is the one right here.'

The man, assuming he is dealing with an airhead blond, asks,

'Tell me lady, 'cause I'm dying to know; how would YOU know

that this is the right cow to be bred?' 'That's simple," she said.

"By the nail that's over its stall,' she explains very confidently.

Laughing rudely at her, the man says, 'And what, pray tell, is the nail for ?'

The blond turns to walk away and says sweetly over her shoulder....

'I guess it's to hang your pants on.'
