LAS VEGAS, Nevada (The Adobo Chronicles) – There was one too many national anthems sung during Saturday’s boxing fight between Filipino Manny Pacquiao and American Floyd Mayweather.

In addition to the Philippine and American national anthems, the Mexican national anthem was also sung just before the boxers entered the ring.

The announcer said the Mexican National Anthem was being sung to commemorate Cinco De Mayo. Many speculated that it was a demand made by Tecate beer (brewed in Mexico), one of the fight’s major sponsors.

Well, an investigative reporting done by The Adobo Chronicles revealed that it was one of the conditions imposed upon by Mayweather when he signed the deal with the Pacquiao camp.

It turns out that Mayweather is a dual citizen — of the U.S. and Mexico. His Mexican connection explains his surname which pays tribute to the month of May, as in ‘Mayo’ in Spanish. As in Cinco de Mayo.

There will certainly be a lot of celebration going on with the Mayweather camp: a unanimous decision victory over Pacquiao, Cinco de Mayo and bottomless Tecate beer!
