Here's a tour of Dublin's Guinness Brewery courtesy of comedian Conan O'Brien — who, of course, is really just there to score some free beer. The running gag is that he must first take the entire tour before hitting the tasting room. He looks at the 9,000-year-lease, explores the ingredients room and watches a video about yeast. There's also a wall of famous people who have visited the brewery, including Queen Elizabeth, Bill Clinton, and Paul Rudd. Conan complains: "I think most of these people did not have to go through a whole tour. I think a lot of them got their Guinness right away."
Finally, Conan makes it to the tasting room where he learns how to pour a perfect pint and serves Guinness to thirsty tourists. He also shares a genius idea: "I tried to make Guinness myself once at home. I took a loaf of pumpernickel bread, put it in the blender and then buried it in the yard for about six weeks. I got sick as a dog."
