A lumberjack had raised his only son & had managed to finance the young man's college education by the only way he knew how, cutting down trees, BY HAND.

The young man had helped his father cut down some of those trees. He knew how hard his father had to work to put him through college.

When the son started college he promised himself the first thing he would do was to buy his father a present that would make the old man's life easier. The son saved & scrimped & finally had enough money to purchase the finest chain saw in the world.

On a school vacation the son asks his dad how many trees could he cut down in one day. The father a large husky man thought and said on a good day he was able to bring down 20 trees. The son gave the father the brand new chain saw & said from now on he would be able to triple the amount and only work half as hard.
The old man was very pleased and said he had the best son in the world. The young man left for school the next morning & wasn't able to return until the next school break, 3 months later.

When he arrived he immediately noticed that his dad appeared run down. He asked if his father was feeling alright. The old man replied that cutting trees was getting harder & harder & now with the new chain saw he was working longer hours but not cutting as many trees as before.

The son knew there was something wrong & thought perhaps the saw he purchased wasn't as good as advertised. He asked to check it out. Upon examining it he checked the oiler & it was full. He checked the gas & it too was full. He yanked on the cord & immediately it roared to life.

His father grabbed him by the shirt & hollered, "WHAT'S THAT NOISE!!!!"
