Season 9, Episode 14: "The Strongbox"

-I was just hanging out at his place. -Really? What's it like?

Is it nicer? Where does he have the couch?

Well, I don't know, but the key problem is solved.

-I hid it at Phil's. -He let you?

No, he doesn't know. See, I hid it without telling him.

So Phil won't be compulsively looking for it like some people.
