Quote from Barney in The Naked Man
Robin: "He said he loved you, but you're not ready to say it back yet" sex. Lily: Forty-three. Ted: "Wingman diving on the friend grenade." Lily: Forty-four. Barney: "The condoms are about to expire." Lily: Forty-five. Wow, this is getting a little hard. Barney: Forty-six!
