Quote from Barney in The Naked Truth
Nora: Let me make one thing very clear to you. I don't date guys who lie to me. Barney: Well, see, I did not know that. My bad. So, from here on in, no more lies. I will never lie to you again. I'm serious. Ask me anything. Nora: Okay. Have you ever successfully gotten a woman in bed by lying to her? Barney: Have I ever... If I'm being totally honest... Yes. Nora: More than once? Barney: More than once... Wow, that's... [clicking tongue] I guess if we're splitting hairs, then, technically... there was a plurality to the times I've lied to women for sex having purposes. Nora: What were they? Barney: Nines and tens mostly. There was a four once. She was a slump buster. But, Nora, after that, I had a run that you would not believe. Man, honesty feels good. Nora: What were the lies? Barney: You want me to tell you every lie I've ever told a woman to get her into bed? Nora: A bed or any other place you had sex with her. Barney: Oh, you're good.
