[flashback:]
Barney: All right, next challenge.
Lily: Oh, this is an all-night thing? Okay. Um... Pick up a girl wearing a garbage bag.
Barney: I'd be Glad to. Just hope she's not too Hefty. And those are all of the brands of trash bags I can think of.
Lily: I'm not done. You also can't use the letter E.
Barney: Challng accptd!

[flashback:]
Barney: Seriously, guys, you're gonna have to try harder than that.
Robin: Challenge accepted.
[later, at MacLaren's:]
Robin: Excuse me, hi. I'm Ryan Gosling's personal assistant. He saw you as you were walking in, and he sent me over to tell you to wait here. Be cool. This is real. Okay? But listen. Ryan is super shy. I know. Heh-heh. Which means if he comes in here and sees you talking to some other guy, he's gonna turn right around and leave. Nod if you understand.
[back at the apartment:]
Robin: Redhead at the bar.
Barney: Challenge accepted!
[later at MacLaren's:]
Barney: Hey there.
Woman: Get away from me!

[flashback to Ted and Marshall talking in MacLaren's:]
Ted: We're not platonic. "Platonish" maybe, if that's even a word. But not platonic. I mean, there's something between us, and there always will be. Man, if this was eight years ago, I'd be jumping into a cab right now to go steal that blue French horn.
Marshall: Well, why don't you?
Ted: I don't know. It just doesn't seem to work that way anymore. I used to be in such a hurry all the time. Everything was so urgent. But now? I don't know, I figure if it's gonna happen, it'll happen when it happens. I'm not going anywhere, she's not going anywhere. What's the rush, right?
