"P.S. I Love You"

Dobler/Dahmer Theory: The theory that when two people are into each other, a big romantic gesture works, such as Lloyd Dobler's boombox gesture in Say Anything. But if one person is not into the other, it comes off as "serial-killer crazy" a la Jeffrey Dahmer.

*In order to seduce women and get rid of clingy ones, Barney invented all kinds of ridiculous, creepy inventions in his apartment:
