Okay. Back on fact stuff...
On this date (June 2nd) 56 years ago "The Corbomite Maneuver" wrapped filming. Between 2006 and 2016, a popular ad campaign for Dos Equis beer featured a debonair, gray-bearded gentleman, identified as “The Most Interesting Man in the World,” who ended each ad with a variation on the slogan — “I don’t always drink beer, but when I do, I prefer Dos Equis. Stay thirsty, my friends.”
If you follow
Star Trek anything on social media you probably know where this is going, because for the past decade memes like the following have been circulating, and continue circulating a half-dozen years after the actor in question retired from his “Most Interesting” role.

The memes identify the actor as Jonathan Goldsmith and claim he appeared as a non-speaking, unnamed redshirt in an episode of the original
Star Trek.
One of those is true.

Even Shatner's official Twitter feed treated it as fact.
The Most Interesting Man in the World was indeed played by Jonathan Goldsmith.
But as to
Star Trek, in an interview with the Television Academy, Mr. Goldsmith dismissed the story:
David M. Gutiérrez: It's fitting you're being sent to Mars [in a commercial], considering you're credited as being a "Redshirt" in the original Star Trek.
Jonathan Goldsmith: No, I wasn't. I've never done that show. I can’t convince the fans of that. They keep sending me pictures of a guy in a red shirt, but it ain't me.
The Most Interesting Matter here is just how stories like this are born, spread, and propagate to the point they’re gleefully accepted as fact when they, in truth, are patently false.
All the details are in the Dos Trequis article (
