As he guides Ted through various outlandish and unsuccessful plays, Robin walks in and is upset to learn Barney lied to her about the playbook. Barney manages to console her while Ted goes back to Jeanette, who shortly thereafter discovers the playbook and ends up trashing Ted’s apartment and destroying the playbook.
