Lily and Barney return to the room, as Lily assures Barney that if he loses his job, he can stay in the extra room at Dowisetrepla. Robin mumbles, "Make sure you bring your own toothbrush." Ted and Marshall try to get her off Marshall's back. Lily says that trying to sleep with seven women in seve days is a cry for help. Ted scoffs. "Barney's whole life is a cry for help. But you don't mess with a man when he's in the middle of a per..." Barney warns him off with his eyes. Ted shuts up. Lily waits, but when he doesn't finish, she's glad to. "What? Perfect week?" Everyone gasps in horror. Lily throws her hands up in disgust. "Oh, perfect week, perfect week, perfect week!" Barney puts down his ice cream, stands, slides by her without letting their bodies touch, and hustles out of the apartment, shuddering all the way. Before he closes the door, he leans back in and hisses. "Arrrrryyyyyyyyyyygh."

Fantasy Nantz Interview: Nantz is stunned, reminding viewers there are two things you never do. "One, you don't open an e-mail from Phil Simms when your kids are in the room, and two, you don't jinx a man going for a perfect week." Barney doesn't know what to say except that Lily's always messing with him. When Nantz suggests she has "a thing for the Barnacle," Barney calls him an astute observer of the human condition.

MacLaren's; Night Seven: Ted and Marshall can't believe Lily jinxed Barney like that. Lily points out that Barney's hitting it off with "Third Martini Girl." When the gang is cheered by his seeming success, Lily laughs at them. "See, there's no such thing as a jinx." Robin, Ted and Marshall gasp in horror. And sure enough, the only thing that could ruin Barney's chances walks through the door: New York Yankee Nick Swisher (in a hilarious faux-hawk). Marshall can't bear to look at his wife, the jinx-er. "Lily, I'm getting my own toothbrush." Heh.

As Barney's mark eyes Swisher appreciatively, Ted figures the fat lady has sung. Robin doesn't get it. Marshall and Ted explain that no guy in the city can go up against a Yankee -- even a retired Yankee can ruin another New York guy's game. Ted got "rack jacked" by Phil Rizzuto, right after he moved to town. Robin can't relate, so Lily says "Let me try to Canada that up for you, eh?" And puts it in terms she can understand: hockey and the Canucks (Lily says "Ca-chucks"). Robin says, "Lily, if one of the Vancouver Canucks walked in here? My panties would drop so hard there would be a hole in the floor, halfway to China." Ted translates: "That's what it's like with the Yankees." Robin grows quiet. "Oh... Barney's screwed."
