Trish: So, ready to make a commitment to your body?
Marshall: I am all about committing myself to my body. I want to drive out to Vermont and perform a commitment ceremony with my body. That was a weird thing to say.
Marshall: What about your hot new trainer? I thought he was stretching you out.
Lily: Oh, it turned out that guy had no affiliation with the gym whatsoever.
Barney: That was the day I was born. I rose phoenix-like from her mentholated bosom and stood Armani-clad and fully awesome
Robin: That story made me want to join that gym, so that when I get strong I can punch you in the face.
Ted: You know what? Let's all do it.
Lily: Yeah, let's all punch Barney in the face!
Barney: But you said I rocked your world. All subsequent worlds that I rocked were only so rocked because of the confidence I earned from said first world rocking.
Lily: Oh, baby, are you still sore?
Marshall: Trish made me do 70 push-ups, but she only gave me credit for 10. Then she had me do a hundred sit-ups, and then she made me cry, using only her words.
