Duel Citizenship: When Marshall and Ted hear about the closing of one of their favorite road trip destinations, they decide to re-live their bachelor days and drive to Chicago. To the behest of Ted, Marshall decides to bring Lily along and she completely alters Ted's plan for a macho weekend. Robin's pride for Canada lands her in troubles when she breaks an American's nose and faces deportation. In order to become an American citizen, Robin starts preparing for the citizenship test with the help of Barney. Lily leads Ted and Marshall to a bed & breakfast catering specifically to couples which makes Ted feel even more isolated and unhappy about the outcome of their road trip. Ted tricks Marshall into leaving the bed & breakfast without Lily so that they could finally attempt to have the trip that Ted had planned. Robin is ready for the citizenship test but after a drunken night Barney must go rescue her from Canada. Robin decides that rather than become a full-fledged American citizen, she will hold on to her love for Canada by applying for dual citizenship. Marshall and Ted reach Chicago but Marshall misses Lily. Ted confronts Marshall about spending time only with Lily and while Marshall is initially offended, the two find a common ground and reunite on the way back to the bed & breakfast. ...
