An Mid-Westener walks into a hardware store and asks for a chain saw that will cut 6 trees in one hour. The salesman recommends the top of the line model.
The Mid-Westener is suitably impressed， and buys it. The next day he brings it back and says， “This chainsaw is defective. It would only cut down 1 tree and it took ALL DAMN DAY！”
The salesman takes the chain saw， starts it up to see what's wrong， and the Mid-Westener says， “What's that noise？”
