Old Jake had cut firewood by hand with a swede saw for a living going on 50 years. He averaged about four cords a day. His son was home from college and watching him work remarked, "You could probably cut 10 times as much if you bought yourself a chainsaw."
"Not interested in those new fangled things," Jake responded.
His son returned to college and Jake began to think that maybe the young guy was right; his old body seemed to ache more and more at the end of the day. So he went into town and bought a brand new top-of-the-line chainsaw.
The first couple days were not very productive--he only cut one cord each day. By the third day he had cut 3 cords but was dead tired. "This is not working," he thought to himself, "My son said I should be able to cut 10 cords a day. I'm taking this stupid thing back."
The next day he was in the hardware store complaining to the sales clerk about his lack of production. "Blade seems a little dull, but not that bad. Let's start it up," the clerk muttered as he pulled the starting cord.
"What the hell is that noise?" Jake hollered.
