One day a redneck walks into a chain saw store and he asks the clerk "Do yall have a chain saw that can cut 6 trees per hour."
The clerk takes him to the best chain saw thay have in the store. so the redneck buys it.
The next day the redneck comes back with the chain saw. The redneck says to the clerk "This thangs a fraud I only cut down one tree and it took me all dang day."
So the clerk looks at it and cranks it up.
The redneck says "how in tarnation did you get it to make that noise."
