Actors Neil Patrick Harris and Cobie Smulders sit down with Entertainment Weekly to talk about the relationship between their characters Barney and Robin on the show How I Met Your Mother.

After Marshall and Barney have an argument, Robin and Lily try to figure out what type of alcohol will get them in the right mood to reconcile.

Barney explains the magic of February thirteenth, or as he calls it, "Desperation Day."

Barney never fails to impress the group with the lengths he'll go in order to get a woman interested in him.

When an invitation arrives for the previous occupant of Ted's apartment, the gang decides to attend the event in her place.

The male characters of the hit TV series How I Met Your Mother are constantly helping each other get into and out of situations. The book Bro on the Go contains the code of honor necessary for maintaining such friendships.
