Meanwhile, Robin and Don, who have established good chemistry on their morning show, hang out with Marshall and Lily at the bar.
Barney confronts Anita, and she asserts that the book encourages women to be powerful and not to rely on untrustworthy men.
When checking the book for a loophole, Barney discovers Anita is the author and devises a plan to seduce her into breaking her 17 dates rule.
Later, Robin admits to Marshall and Lily that when Anita was a guest on her show, they hatched a plan to teach Barney a lesson.
Barney heads to the shooting range and apologizes for preparing a wonderful date for Anita when he had never treated Robin that way.
After finishing his story, Barney is fined $500 for the misdemeanor, and watches the skyline as Don and Robin kiss during the fireworks display that marks the ending of the "super date".
