"Yo soy Conan! Mi nombre es Conan. Conan O'Brien!" O'Brien said. "I was a little worried my Spanish wouldn't be good enough here in Cuba, but now I think I'll be OK."

O'Brien did his best to fit in with ferocious dogs, some elderly women and two very confused grocery store employees.

But his mediocre Spanish and keen ability to upset the country's canines made it a little difficult, and it was, in true O'Brien fashion, very silly.

As a writer for Uproxx notes, "He isn't changing much of his attitude to adjust to the nation's customs."

But O'Brien told CNN before the episode aired that he wasn't trying to insult Cuba in any way.

"I did not want this, in any way, to be snarky or me being cutting about their culture. I wanted to go and, in a lot of my remote segments, the joke is on me. I'm the fish out of water. And that's really the spirit that I wanted to bring to it."

The "Conan in Cuba" episode marked the first time in more than 50 years that an American television show had been filmed in Cuba.
