Lily: Where's the poop, Robin?
Robin: Excuse me?
Lily: When I was a kid, I had a dog named Bean. Whenever he made the face that you're making right now, you just knew he pooped somewhere in the house. Where's the poop, Robin?
Robin: I don't know what you're talking about.
Lily: Where's the poop, Robin?
Robin: There's no poop.
Lily: Where's the poop?

Robin: Hey, guys.
Lily: Where's the poop, Robin?
Robin: How do you do that? You are like a bomb-sniffing dog, except with poop. You are a poop-sniffing dog.
Marshall: I think that's just called a dog.
Lily: Where's the poop, Robin?

Marshall: Oh. Wow. Back already. How was flying solo? And by "solo," I mean so low that you got shot down.
Barney: Look, I didn't get shot down. Trust me, I'll get the yes. Barney Stinson always gets the yes. This is all part of the plan. After initial contact, I'm now in the ignoring phase.
Lily: Barney, why can't you just take a girl out to dinner like a normal person?
Barney: Golden rule: I do not buy dinner to get the yes. Dinner's a very intimate activity. It requires a level of connection and eye contact that sex just doesn't. Call me old-fashioned, but I need to have sex with a girl at least three times before I'll even consider having dinner with her.
