Marshall: All right, I don’t think this is going to help.
Barney: Do you know why you’re not over Lily yet? It’s because you can still picture her naked. You can’t get over a woman until you can no longer picture her boobs. The average male brain can only store a finite number of boob images or ‘b-pegs’. And your hard drive is filled to capacity with Lily’s.
Marshall: There are a lot of them.
Barney: Well, they won’t go away until you overwrite them with images of other women’s boobs. Now, this journey may take as many as a million boobs, so we begin here tonight, my friend.P/S: Credit to How I Met Your Mother Season 2 Episode 1.
