The only bit of logic-based public bathroom humor I know is: the difference between men and women is that between the statement [P and not Q] and the statement [Q and not P].

I think, therefore I laugh.

In the stock market... You can be right for the wrong reasons or wrong for the right reasons.

Mathematicians are a bit like the laconic Vermonter who, when asked if he's lived in the state his whole life, replies, Not yet.

There is something inhuman and vaguely pornographic about statistics... Pornography, on the other hand, with its loosely bound sequences of storyless sexual couplings often has the feel of a statistical survey.

Uncertainty would be the only certainty there's, and realizing how to stay with insecurity could be the only protection

Defined broadly enough, mathematics encompasses everything.

How many pizzas are consumed each year in the United States? How many words have you spoken in your life? How many different peoples names appear in the New York Times each year? How many watermelons would fit inside the U.S. Capital building? What is the volume of all the human blood in the world?

I used to be surprised and even depressed when I met someone I had admired and discovered him or her to be a jerk or, perhaps worse, rather common.
