Upon leaving, the brunette tells her sister, 'When I get there, if I decide to buy the bull, I'll contact you to drive out after me and haul it home.'
The brunette arrives at the man's ranch, inspects the bull, and decides she wants to buy it. After paying him, she drives to the nearest town to send her sister a telegram.
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. I need her to hitch the trailer to our pickup truck and drive out here so we can haul it home.'
The telegraph operator explains that it will cost 99 cents a word.' Well, after paying for the bull, the brunette realizes that she'll only be able to send her sister one word.
After a few minutes of thinking, she nods and says, 'I want you to send her the word 'comfortable.'
The operator shakes his head. 'How is she ever going to know that you want her to hitch the trailer to your pickup truck and drive out here to haul that bull back to your ranch if you send her just the word 'comfortable?'
The brunette explains, 'My sister's blonde. The word is big. She'll read it very slowly.... 'com-for-da-bul.'
