A farmer walked into a hardware store and asked for a chain saw that could cut six trees in one hour. The salesman recommended the top of the line model. The Iowan was suitably impressed, and bought it.
The next day he brought it back, saying, "This chainsaw is defective. It would only cut down one single tree and it took all dang day!"
The salesman took the chain saw. He started it up to diagnose the problem, and the farmer jumped backward, startled.
He yelled, "Lan'sakes! What's that noise?"
