The Dos Equis Guy meme, officially known as 'The Most Interesting Man in the World,' originated from a highly successful advertising campaign for Dos Equis beer that began in 2006. Starring actor Jonathan Goldsmith, the commercials featured a sophisticated, older gentleman performing legendary feats, concluded by his signature catchphrase: 'I don't always drink beer, but when I do, I prefer Dos Equis.' The internet quickly adopted this as a phrasal template (a 'snowclone'), allowing users to highlight specific habits or rare behaviors with a touch of worldly humor. It remains one of the most recognizable and enduring image macro formats in meme history.
