An accountant

An accountant is in a car travelling with a farmer client around his farm. They pass a large mob of sheep and the farmer says, "You're pretty good with numbers, Keith. How many sheep do you reckon are in that paddock?" The accountant looks at the sheep for a moment and says, "One thousand, eight hundred and thirty two." The farmer is amazed. "Exactly right", he says. "How did you work that out so fast?" "Easy," says the accountant "I counted the number of feet and divided by 4."
