As far as I’m concerned, there was not nearly enough footage of Barney’s nightmares in this week’sHow I Met Your Mother. The little bits we got of Ted, Marshall, and Barney’s "Weekend at Barney’s" adventures were spot-on, hilarious parodies.
Barney’s anxiety over his unused playbook ideas happened to coincide with Ted’s breakup with crazy Jeannette. Right as Ted was about to do the typical Ted thing and crawl back to Jeannette, Barney and his back up copy of the Playbook intervened. Ted became Barney’s way of acting out plays from his playbook without technically violating the rules of his relationship with Robin.
