Sumo in Vegas

Most of the events described in Freakonomics took place, or still take place, in the continental U.S. — except for the chapter describing how sumo wrestlers collude to throw matches. We’ve gotten a surprising number of e-mails from readers in Japan with interesting sumo comments but most of us don’t have regular access to live sumo. At least we didn’t have access until this weekend: click here for a preview of a grand sumo tournament at the Mandalay Bay. Remember: if on the last match of the tournament, you have a chance to bet on a 7-7 wrestler who is facing an 8-6 or 9-5 wrestler, do it.
