A businessman has been learning to be a balloonist and takes his first solo flight. Unfortunately the wind gets up, he is blown off course and is forced to land. He is in a paddock close to a road but has no idea where he is. He sees a car coming along the road and hails it.
The driver gets out and the balloonist says, "Excuse me but can you tell me where I am?"
"Yes, of course", says the motorist. "You have just landed in your balloon and with this wind you have obviously been blown off course. You are in the top paddock on Steve Pringle's farm, 8 miles from Stonehenge. Steve ploughed the field last week and sowed barley seeds. Also, there's a bull in the paddock. It is behind you and about to attack you."
At that moment the bull reaches the balloonist and tosses him over the fence. Luckily he is unhurt. He gets up, dusts himself off and says to the motorist, "I see you're an accountant".
"Good Grief", says the other man, "you're right. How did you know that?"
"I employ accountants", says the balloonist. "The information you gave me was detailed, precise and accurate. Most of it was useless and it arrived far too late to be of any help."
