[flashback to Barney with Honey in her apartment:]
Barney: I mean, I shouldn't be surprised. Clearly, he wants nothing to do with me.
Honey: Oh, honey.
Barney: I mean, why else would he let 30 years go by? He's ashamed to have me as a son.
Honey: Oh, honey, he's not ashamed of you. He's ashamed of himself. I mean, look at you. You're do so great without him. I mean, you have an airline and three Nobel Prizes, and you play for the Yankees.
Barney: Four. Four Nobel Prizes.
Honey: Four. See? That is impressive. I mean, how many does he have?
Barney: Only three.
Honey: Well, there you go.
