Quote from Barney in Single Stamina
Barney: [enters] Clam Bake. Staten Island. Who's in? Okay, I didn't have high hopes for that one. Okay, here's my thing. If gay guys start getting married, then suddenly the whole world's gonna be doing it. That's how it works. They start something, then six months later, everyone follows. Like now everyone gets manicures. Ted: I don't get manicures. Barney: Okay, then like how... Like getting your chest waxed. Lily: [gasps] You get your chest waxed? Barney: You know what I mean! Gay marriage is going to cause single life, as we know it, to die out. Think of how the American family will be strengthened.
