Saw
From Encyclopedia Of Stupid
Saws are stupid.
A saw is a veeeeery useful tool. It can be used for cutting stuff, like pets or emo kids. If you are using a saw regularly, you should wear a helmet, as a precaution. You don't want the saw to eat your head.
History of saws
The first saw was created by a caveman named Bill Gates sometime before 1975. Bill Gates thought that he was a clever boy, and patented it. The next year, he made a crappy computer, and since that day, his free time activity is to create the crappiest products in the world. And it's all because of the saw.
Cutable stuff
If you see a cake, you can cut it, unless it's a concrete cake. To not attempt to cut off your sex organ, unless if you are male.
VERY IMPORTANT NOTE
Please, use a saw to cut off the head of Bill Gates.
