Robin: So when was the last time you saw him?
Barney: It was that day, July 23, 1981. My mom got pretty mad that he let me destroy a New York City landmark.
Robin: Moms.
Barney: He never came around anymore after that. Think he moved away.
Robin: Well, maybe the security guy had it wrong. You never know...
Barney: But you do know, you do know. That's the thing. You know. He's my dad.
Robin: Barney, do you want...?
Barney: I don't want to do anything. Don't tell anyone about this, okay?
