How I Met Your Mother Season 4 Quotes

Ted [to Stella in his dream encounter]: You picked the wrong guy.
Stella: Ted?
Ted: You picked the wrong guy. You made a really, really, really bad choice. What were you thinking? That guy? Are you kidding me? Have you learned nothing in the last eight years? You're just gonna regret this. You know that, right? You are going to regret this, and now there is nothing you can do about it because it's too late. All you can do now is go up there and start your crappy, disappointing life that will never be nearly as happy as the one you could have had with me. Good-bye.

Stella: I know
