Barney: Ted, you've heard of the golden rule, right? "Love thy neighbor?"
Ted: Uh, actually, it's "Do unto others as you would have them do unto you." It's from the bible.
Barney: Damn it, Ted, I've worked out this whole thing where the golden rule is "love thy neighbor", okay? Now the golden rule is "Love thy neighbor". But, there's one rule above it: the platinum rule: "never ever, ever, ever, love thy neighbor."
