Quote from Barney in The Rebound Girl
Ted: It's genius! Instead of throwing away your life marrying some girl, you just go splitsies on a kid with your best bro! Barney: I wouldn't have to choose between dating and having a family. Hell, I could bring the kids on dates! Ted: And a broken home? Um, what's that? Our kids will never know, 'cause we're never gonna split up! Barney: Why would we? I mean, sure, when your wife walks in on you banging a hot flight attendant, you get a divorce. But when your bro-parent walks in on you banging a hot flight attendant... Ted: You get five of these bad boys, right up high! Barney: And you totally join in, right?! Oh, no, there's the line. Ted: That's the line. We found the line. It's good we know where it is.
