MacLaren's: Barney tells Robin that moving away is a group decision. When Ted tries to point out that it should be Robin's decision, Barney says, "Stay out of this, Brigitte Nielsen or Dolph Lundgren from Rocky IV." A beat. "We need Marshall and Lily."
Bedroom: Lily's going on about how Cabbie Barney (who, if you've drifted off, was Actual Barney) looks nothing like Actual Barney. She thinks he looked like a Vietnamese pot-bellied pig. DING DING DING on the pig part. Oh wait, that's not what she said. She thinks he was an Asian man with greying hair, a soul patch, and a pot belly." Marshall (agitated): "Have you completely forgotten what Barney looks like?" And now, we're watching Laverne & Shirley, so Barney plays Lenny or Squiggy -- barging into their BEDROOM. "You guys banging?" They scream, then Marshall asks, "Why are you in our bedroom?" Next, Robin enters, they scream more, and then: "Why are you in our bedroom?" Blond Ted enters to more screams, then Marshall asks, "Why is Ellen DeGeneres in our bedroom?" After he's done laughing at Ted's expense, Barney looks around and notes the candles and flowers. "I guess Marshall 'forgot' to tell you: the fifth doppelganger was me." Lily then accuses Marshall of lying to her, and rather than explain that he was trying to tell her the truth, he rationalizes it, instead. You deserve better, so let's move on.
So yeah, the gang has just burst into their married friends' bedroom to announce Robin's Chicago job opportunity. Barney begs everyone to talk Robin into refusing the job, but Robin says she's already come to her decision. She has to take it. Commercial. Don't worry. The episode is only halfway through, she's not taking it. This is just the precursor to more predictable sitcom glurge.
MacLaren's: Barney, Blond Ted, Lily and Marshall sit around the table. As Ted bemoans the potential loss of Robin (that will not come to pass), the gang starts having another telepathic conversation. Lily's Mind: Guys, maybe this is the depression talking, but is Ted's hair starting to look kinda good? Marshall's Mind: Thank God. I thought I was the only one. Barney's Mind: He looks like a freaking movie star. Ted (aloud): "Oh, and by the way, this [indicates hair] was a huge mistake. I'm changing my hair back." The gang winces and agrees.
