The Cost of Brain Transplants

A man was told by the doctor that he needed a brain transplant. The man was distraught, but he started asking the doctor about his options, and the doctor began to show him three different brains.

The doctor told him, "The first brain we have is a truck driver's brain. He was a moral man, a kind man and a very good family man that made about $50,000-$75,000 per year. We can sell you this brain for $1 million!"
The doctor went on, "The second brain is that of a Harvard law professor. He was a good moral man, very religious, very kind, he always was charitable and helped others, and he made about $250,000. We can sell you that brain for $2 million."

"The third brain is that of a banjo player, and we get $20 million for that brain!" He then shut his mouth and didn't say another word.

The man looked at the doctor and asked, "How come the banjo player's brain is so expensive?"

The doctor replied, "Obviously you don't know much about banjo players! A banjo player's brain is barely used!"
