Quote from Barney in A Change of Heart
Barney: I mean, Nora's great. She's wonderful. But... Lily: What time was your dinner reservation? Barney: Last night? 8:30. Lily: What did his heart do at 8:30? Dr. Kirby: It... literally skipped a beat. Lily: Your heart's talking to you, Barney. Do you have the guts to listen to it?
