Robin: It was me! I was a stalker. It was back in Canada. I liked a guy and he didn't like me, and... Well, I got a little obsessed. I'd fill up my journals all about him. And eventually, there may have been a teensy-weensy 50-meter restraining order.
Barney: Fifty meters? That's like... four years. Wow. You must have been a total nut bag.
Robin: I wasn't. Ted is right. There is a fine line. Anyone can cross it and get obsessed.
Barney: Yeah, if you're a total nut bag.
