Paddy 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.
Paddy takes the chainsaw home and begins working on the trees but after working for over three hours he only cuts down two trees.
The next day Paddy gets up early in the morning and works until sundown, but still only manages to cut down five trees.
The very next day he takes the chainsaw back to the store and says it doesn’t work properly.
“Hmm, it looks okay,” says the server, and starts the chainsaw. Paddy jumps back in shock and cries, “What’s that noise?!”
