A man goes to a tool store to buy a chainsaw. The server sells him the top-of-the-line model, saying that it will cut through over 100 trees in one day.
The man takes the chainsaw home and begins working on the trees but after working for over three hours he only cuts down two trees.
“How can I cut for hours and hours and only finish two trees?” he asks himself.
The next morning he gets up early in the morning and works until nighttime, but still only manages to cut down five trees.
The very next day the man brings the chainsaw back to the store and says it doesn’t work properly.
“Hmm, it looks okay,” says the server, and starts the chainsaw.
The man jumps back in shock and cries, “What’s that noise?”
