A redneck walks into a department store and asks the clerk for a chainsaw that will cut 6 trees in an hour. The clerk tells him he should try the top of the line model. The redneck buys it and goes home. The next day, the redneck comes in again and angrily tells the clerk that the chainsaw is defective,he could only cut down 1 tree and it took him all day. The clerk takes the chainsaw to see whats wrong with it. As he starts it up the redneck says... Heck whats that noise?
