"The Most Interesting Man in the World" is giving up beer for tequila.Actor Jonathan Goldsmith appeared as the sophisticated, eccentric and worldly pitchman for Dos Equis beer for nearly a decade. He's now promoting Astral Tequila.In a new ad, the 78-year-old Goldsmith nods at his Dos Equis days by raising a glass of tequila and saying, "I told you I don't always drink beer."Dos Equis announced Goldsmith's departure from the long-running ad campaign last year. It has continued the campaign with a younger actor.
