The Bad Chainsaw!

The dealer tells him, "Look, I have a lot of models, but why don't you save yourself a lot of time and aggravation and get the top-of-the-line model. This chainsaw will cut a hundred cords of wood for you in one day."

He thinks there is something wrong with the chainsaw. "How can I cut for hours and only cut two cords?" the man asks himself. "I will begin first thing in the morning and cut all day," the man tells himself.

The man is convinced this is a bad saw. "The dealer told me it would cut one hundred cords of wood in a day, no problem. I will take this saw back to the dealer," the man says to himself.

Then the dealer starts the chainsaw, to which the man responds, "What's that noise?
