A peasant buys a chainsaw that is guaranteed to cut 1001 trees.
One day he goes into the forest to cut wood. After cutting 100-200-300... 1000 trees, at the 1001-th, the chainsaw breaks. It simply dulled and did not cut anything anymore.
Angry, the man goes to the store to make a complaint.
The seller takes the chainsaw, looks at it for a moment, then pulls the starter handle and the chainsaw works again: “brrrrrrr-brrrrrrr-brrrrrrrr”.
The peasant, surprised and somewhat suspicious, exclaims:
-Oh, man, but it did not make that noise until now!
