Okay kiddo, so Chainsaw Al is a person who worked at a big company called Sunbeam. He became really famous because he was really good at making Sunbeam lots of money.
But the problem was that he wasn't always doing things the right way. Sometimes he would make things look better than they really were, or he would tell big lies to make the company look good.
Even though he made Sunbeam lots of money, he eventually got in big trouble for not being honest. That's why people call him Chainsaw Al - because he was really good at cutting things down, but it wasn't always the right thing to do.
So even though he was a successful businessman, he learned that being honest and doing things the right way is really important, especially in the long run.
