Quote from Ted in The Duel
[flashback to Ted and Marshall playing video games:] Marshall: So, when Lily and I get married, who's gonna get the apartment? Ted: Oh, that's a tough one. You know who I think could handle a problem like that? Marshall: Who? Ted: Future Ted and Future Marshall. Marshall: Totally. Let's let those guys handle it. [back:] Ted: Damn it, Past Ted.
