Marshall: I think we've all noticed a few curious mannerisms. Or rather, doggerisms.
Ted: And the best part is, he got his shots.
Marshall: You are so playful.
Ted: Nice job fetching those.
Lily: Scooby, sit.
Marshall: So, Scooby, we were thinking if you're going to be hanging out with our Robin, you should be properly vetted.
Ted: We hope our nosiness doesn't give you "paws".
Lily: How did you meet? Tell us the "tail".
Marshall: Yes, how did you "whisker" off her feet?
Ted: Shed a little light on the matter.
Lily: Did you send her an e-mail or did you "collar"?
Robin: Guys, just stop hounding him.
Marshall: We don't want your new guy to "flea".
Lily: We're just trying to make sure he's not a heel.
Ted: So, moving from Canada, that transition must have been pretty "ruff".
Lily: Oh, I bet it was an "Incredible Journey".
Marshall: What part of Canada is that? Speak.
Marshall: Just make sure it's not a high-frequency whistle, because we don't want to torture Robin's boyfriend.
Barney: No, Scooby, you, uh... stay!
Lily: Scooby got out!
Lily: He must've figured out how to open it himself.
