Needing a place to stay, Lily moves in with Barney, and it's only a matter of time before they're sleeping together. Elsewhere, Marshall spends some quality time with a new friend, who just happens to be a guy.

When Ted's new girl becomes jealous that the story of how he and his pals met is better than the story of how she and Ted met, her ranking on Barney's "crazy scale" skyrockets.

When the gang finds out that Ted is taking his doctor on a date, they try to convince him, through examples of their own toxic experiences, why it's never a good idea to get into a relationship with someone you see on a regular basis.

When a guilt-ridden Barney breaks the "Bro Code," he struggles with the ramifications of his misstep.

Marshall and Barney play a joke on Ted and pretend to be a girl that he is having a "text" relationship with.

After breaking up with Robin, Barney jumps back into the dating scene with the classic moves from his "Playbook."
