[Marshall and Lily talk about Lily's program in San Francisco]
Marshall: So that's it? We're breaking up?
Lily: Marshall, I'm sorry. I just, I just need to go to San Francisco and do this art program and-and figure out who I am outside of us, and the only way I can do that is if...if we don't talk for a while.
Marshall: For a while. Try never, okay? You walk out of that door, and we're done. You're never going to hear my voice again! [segue to Marshall talking to Ted] I should call her.
Ted: No, no, if you call her when she asks you not to, you're just gonna look weak and you're gonna regret it. Whenever you feel like calling her, you come find me first... and I will punch you in the face.
Marshall: You're a good friend, Ted.
