[Flashback to 1982, where young Barney and James are watching TV:]
Future Ted: [v.o.] The truth is, Barney and James got a lot of different explanations from their mom over the years.
Loretta: Well, boys, you look different because when I was pregnant with you, I only ate vanilla ice cream. And when I was pregnant with you, can you guess what kind of ice cream I ate?
James: Coffee?
Loretta: No, James, I ate chocolate ice cream. But I did drink tons of coffee when I was pregnant with both of you. Can't smoke without my coffee.
[flashback to 1984:]
Loretta: I don't know, boys, I guess it's just one of those things.
[flashback to 1986:]
Loretta: Stop asking me! You know what you two are? You're little racists!
