Quote from Barney in A Change of Heart
Future Ted: [v.o.] Kids, the heart is a mysterious muscle. You never really know what's going on in there. So after Uncle Marshall lost his father, he decided to get his heart checked. And so did I. And so did Lily. And so did Robin. And then Marshall went again just to be sure. There was only one holdout. Barney: I don't need to go to a heart doctor. I drink every day, I sleep three hours every night, and I have multiple sex partners. I'm doing everything right.
