Today marks the 154th anniversary of Cinco de Mayo, a commemoration of the Mexican victory over the French at the Battle of Puebla on May 5, 1862. 
 
While seen as a relatively minor holiday in Mexico, in the United States Cinco de Mayo has grown into a much wider celebration of Mexican culture and heritage, particularly in areas with large Mexican-American populations.
 
To get you in the mood for the occasion, here below we list some suitably Mexican-themed records from the Guinness World Records database.
