When their father dies, in his will he leaves them his farm. The 2 sisters decide to live on the farm. After a couple of years they have financial problems because their cattle and crops kept dying. So as a last resort the brunette told the blonde that she found an ad in the newspaper about a man who was selling top grade bull.
She told the blonde that she would go to see him and maybe buying a bull. The brunette also told the blonde that if she buys the bull that she would have to bring a trailer on the back of the truck so they could haul the bull home. The brunette said "I'm going to bring $600 with me."
So the brunette went to go see the man and decided she would buy the bull. The man told her that he would sell it to her for $599 and no less. So she says yes.
The brunette then continued to the telegraph office so she could send a message to her sister. She walks in and says "I would like to send a message to my sister saying that I have bought the bull so you have to put a trailer on the back of the truck so that we can haul the bull home." The man in the office tells her that messages are 95¢ per word. The brunette only has $1 left so she decides that she will send a single word.
She tells the man "I only have $1 left but i would simply like to send the word COMFORTABLE." The man asked how her sister would know that she wanted her to put a trailer on the back of a truck so that they can haul a bull home. The brunette said "My sister is a blonde she'll read it slow"
The blonde got the telegraph and read it aloud "COM FOR DA BULL"
