Homer: Doh, the Broncos won! Why didn’t I bet on them like Professor Pigskin told me too?HT: Blogging Wall Street.
Lisa: Who’s Professor Pigskin?
H: He’s a pig who can predict football winners in advance.
L: How is that possible?
H: Because he’s got something no gambler’s ever had. A System! I’ve got the pamphlet four weeks in a row and every time the pick of the week has been right on the money.
L: Ohhhh. I get it. Every week they send out two pamphlets, half picking one team and half picking the other. Eventually, there’s a small group of people who only receive the correct predictions and think Professor Pigskin is always right. That’s when they ask for your money.
I wonder if Professor Pigskin picks stocks?
This is similar to an example I regularly use in class to illustrate how quite a few mutual funds could end up beating the market five (or even ten years) running just by chance.
Now I'll use Professor Pigskin instead.
