Dr. Kirby: What happened at 8:46 p.m. last night?
Barney: Well, let's see... Uh, Wheel of Fortune, naked push-ups, naked chin-ups... I was at dinner.

Nora: This might be a little forward, but do you have a bomb strapped to your chest?
Barney: This? No, no. It's a heart monitor. It's a medical thing.
Nora: Oh, I'm so sorry. I've been trying not to stare at your chest all night.
Barney: [chuckles] What's that like?
