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.'
