Quote from Ted in The Final Page (Part 2)
Marshall: That's huge. Ted: Yeah, that's why Barney's not coming tonight. He's getting engaged. And I knew that I had to tell Robin. Marshall: But? Ted: I may have, uh... asked her to be my date instead. What is wrong with me? Deep down, is there still some crazy part of me that thinks I'm gonna wind up with Robin? Am I that deluded? If so, I need to grow up. Oh, um, by the way, I'm breaking a jinx swear here, so don't tell Barney or he gets to whack me in the nuts three times with a Wiffle ball bat. Marshall: Sure, pretty standard. Ted: Robin deserves the chance to go after Barney one last time if that's what she wants. Thanks, buddy. This helped. I'm gonna go tell her. Marshall: One quick thing. Ted: Yeah. Marshall: Don't.
