Conan's best bits always come in these unscripted moments. And here he doesn't disappoint, taking a routine trip to the Guiness Brewery in Dublin, Ireland to great comedic heights—simply by being a huge asshole to the tour guide and Brewmaster.

Also, how the hell did Jorge Garcia get his picture on the Wall of Fame next to Obama and Clinton? The dude has totally "lost" his career. I'll see myself out.
