Quote from Barney in Lucky Penny
Barney: Training for a marathon. [scoffs] Marshall: What? Barney: You don't need to train for a marathon. You just run it. Lily: You're kidding, right? Barney: Not at all. I could run a marathon anytime I wanted to. Marshall: So like tomorrow, you think you could wake up, roll out of bed, and just run the New York City Marathon? Barney: Absolutely. Robin: Barney, we're talking about 42 kilometers. Ted: Thanks, Canada. I'll take it from here. Barney, it's like 26 miles. Barney: Here's how you run a marathon. Step one, you start running. There is no step two.
