Future Ted: [v.o.] Now, kids, it had been a rough couple weeks for Barney. First, he cheated on his girlfriend with Robin, then he broke up with his girlfriend for Robin, then Robin chose Kevin over him. So he was kind of in a bad place.
Ted: Hey. You all right?
Barney: Why wouldn't I be all right? Barney's single again! It's what America's been clamoring for.
Ted: You just went through a break-up. That's usually when people do something crazy. If you were a girl, you'd have cut bangs and be dating you by now. Just promise me you won't do something crazy.
Barney: I promise I won't do something crazy.
Future Ted: Don't worry, he's gonna do something crazy.
