Gotta tell this. Read it somewhere a few years ago:
John von Neumann, one of the most incredibly intelligent mathematicians of the twentieth century, called his wife from another city. Was on a flight, switching from one plane to another. He had two questions:
(1) Where was he going?
(2) And why was he going there?

Remember (uh, maybe a different word is more appropriate here): If you forget, it's not necessarily forgetfulness, it's probably genius.
