Weezer, proud purveyors of the viral hit of the year, have taken to YouTube again to give clues as to what cities their upcoming tour might hit. Using The Red Album second single “Troublemaker” as its soundtrack, the video dubbed “21″ flashes photos of places and people in rapid-fire order. From what we can identify (with a hat tip to the Weezer Website’s commenters), the video opens with a shot of Harvard University (Cuomo’s alma mater) and then rifles off scenic shots of New York City, Atlantic City, Philadelphia, etc. Weezer also has some fun with the word association, hinting that a photo of John Denver equals Denver, Colorado, and featuring the newest Dodgers acquisition Manny Ramirez as a nod to Los Angeles. The panda bear likely stands for San Diego and its famed zoo, and the guy from Dallas obviously means Dallas. Check out the video above to see if you can decipher all the stops.
