False Positive: Upon hearing the news that Marshall and Lily test positive from a home pregnancy test, the gang assesses the meaning of their lives. Lily and Marshall freak out about the news and start to panic about becoming parents and question if they are ready to have kids. They soon discover they are not really pregnant, and are surprisingly happy about it which sends everyone into a tailspin.  Robin debates whether she should take a job as the "coin toss" girl on a TV game show hosted by Alex Trebek or accept the offer to be a researcher position for the World Wide News, which has always been her dream.  Barney debates how he should spend his hefty bonus- on frivolous gifts ala Oprah, with "Barney's Favorite things," and a diamond suit or whether he should donate it to the church organization that helps outfit the less fortunate for job interviews. Meanwhile, Ted has been trying to help his friend Punchy plan his wedding since he is best man and Punchy panics that he may not be ready to get married.  However, as the gang waivers about these decisions, Ted loses it and encourages everyone to embrace the Christmas spirit and sets everyone straight, encouraging them all to make the right decisions- Robin accepts the news job, Marshall and Lily embrace having kids, Punchy gets over his cold feet and Barney donates all his suits to charity.
