Although this item is nothing more than a seemingly obvious setup for a groan-inducing pun, we've been receiving "Is this true?" inquiries about it from readers every year since 1997 (the year the Academy Award-winning film Titanic was released), particularly around May 5th (i.e., Cinco de Mayo). We don't know why this joke tends to produce more inquiries than similar long-form puns, but we can hazard a few guesses:
- The level of detail found in the setup (i.e., specific names, dates, and places) is atypical and distracts readers into considering the piece as factual rather than humorous.
- Many non-Mexicans are completely unfamiliar with the history and significance of the Cinco de Mayo celebration and are therefore inclined to read this joke as a genuine explanation of its origins.
- With the ongoing controversy over the implementation of immigration reform in the U.S., some people wishfully cling to the notion that a trivializing description of an important aspect of Mexican culture is actually true.
Not that the "Sinko de Mayo" really needs any serious debunking, but for completeness' sake we note that the final destination of the Titanic was in fact New York (not Vera Cruz, Mexico), the great ship was carrying no jars of mayonnaise among its cargo, and Hellman's brand mayonnaise was not sold or manufactured in England until fifty years after the Titanic's ill-fated voyage.
