How I Met Your Mother2005

Barney Stinson:
[At a strip club] Do you know why you're not over Lily yet? It's 'cause you can still picture her naked. You can't get over a woman until you can no longer picture her b*obs. It's a scientific fact. The average male brain can only store a finite number of boob images, or BPEGs and your hard drive's filled to capacity with Lily's.

Marshall Eriksen:
There are a lot of them.

Barney Stinson:
They won't go away until you overwrite them with images of other women's b*obs. Now, this journey may take as many as a million b*obs so we begin here tonight my friend. Two at the time. Those count as four.
