Ted: He means well. Well, actually, I'm not sure that's true.
Don: I think he's awesome. But I feel bad for any woman with the kind of low self-esteem who would actually date a guy like that.

Barney: I like you, Don. We both love a good Scotch. We both enjoy my compelling stories. And we both dated Robin.
Future Ted: [v.o.] Now he knew.
