Persi Diaconis, MIT mathematician, has been quoted to the effect that if you look at a large enough population over a long enough time period then "any damn thing can happen."

How's this for an illustration: "The [Boston] Celtics won their first championship against St. Louis (1957); the [Boston] Bruins broke a 41-year Stanley Cup drought against St. Louis (1970); and the [New England--c'mon, it's basically Boston] Patriots won their first Super Bowl against St. Louis (2002)."

And Boston just beat who to win the World Series?

Any damn thing can happen.
