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.
