Comfortable

There is a blonde and a brunette that own a ranch that is going to be sold if they cant increase the cow herd, so the brunette goes to find a bull for the herd and tells the blonde she will fax her when she is ready so the blonde can take the truck, hitch it to the trailer and come get the bull. The brunette takes $60 and goes to a neighboring ranch. She finds a bull and pays $59 for it. Then she goes and tries to send the fax, but the cost is $.99 per word.

The brunette thinks a minute and then says to just send the word "comfortable".  The operator looks at the brunette funny, so she says " Don't worry, my sisters a blonde so she'll read it slow"
