Farmer Brown, from Minnesota, had a bull that he was quite proud of. One day he looked at the bull and noticed his eyes were crossed. That was disconcerting, because he knew he couldn’t get huge stud fees for a defective bull. He called the local vet who came right over. The vet assured him he could solve the problem.
“Farmer Brown, you stand in front of the bull and watch his eyes. I will insert this straw into the bull’s rectum and blow. When the eyes uncross, yell stop.”
The vet did just that, and sure enough after a few minutes of blowing, the eyes uncrossed. Farmer Brown was thrilled. Several months pass and again he sees the eyes cross.
He says to himself, “I better call the vet. No, wait a minute. Last time I called the vet, he charged me $250.00 for something that only took a few moments. I will do it myself.”
He went to the barn and called his trusty farm hand, Luke.
“Luke, we have a problem here and this is what I want you to do. I will put this straw in the rear of my bull and blow. You watch his eyes, and when they uncross, tell me and I will stop blowing.”
Farmer Brown started blowing and blowing and nothing happened.
Finally, he said, “You know, maybe I am not strong enough, Luke. Lets trade positions and you blow and I will watch.”
Luke went over to the bull, pulled out the straw, turned it around and reinserted it.
“What the hell are you doing, Luke?” says Farmer Brown.
“What do you think? I ain’t blowing on the same end that you did!”
