Barney: All my life I have dared to go past what is possible.
Interviewer: To the impossible?
Barney: Actually, past that. To the place where the possible and the impossible meet, to become ... the possimpible.
Lily: The possimpible? Really?
Barney: Inventing your own word shows creativity and vision.
Barney: That's what corporate America wants: people who seem like bold risk takers, but never actually do anything.
