George W. Bush went to see the doctor to get the results of his brain scan. The doctor said: "Mr. President, I have some bad news for you. First, we have discovered that your brain has two sides: the left side and the right side."

Bush interrupted, "Well, that's normal, isn't it? I thought everybody had two sides to their brain?"

The doctor replied, "That's true, Mr. President. But your brain is very unusual because on the left side there isn't anything right, while on the right side there isn't anything left."
