Two sisters, one blonde and one brunette, inherit the family farm.
Unfortunately, after just a few years, they are in financial trouble.
In order to keep the bank from repossessing the farm, they need to
purchase a bull so that they can breed their own stock.

The brunette balances their cheque book, then takes their last $600
dollars out west to another farm where a man has a prize bull for sale.

Upon leaving, she tells her sister, "When I get there, if I decide to
buy the bull, I'll contact you to drive out after me and bring it home."

The brunette arrives at the man's farm, inspects the bull, and decides
she does want to buy it. The man tells her that he can sell it for $599, no
less. After paying him, she drives to the nearest town to send her
sister a telegram to tell her the news.

She walks into the telegraph office, and says, "I want to send a
telegram to my sister telling her that I've bought a bull for our farm. I need her to hitch the trailer to your pickup truck and drive out
here to bring that bull back to your farm if you send her the word, ‘comfortable'?"

The brunette explains, "My sister's blonde."

"She'll read it very slow."
