The end of How I Met Your Mother has Neil Patrick Harris  and Jason Segel  in a Broadway state of mind. During an appearance on Bravo's Inside the Actors Studio, someone in the audience asked Harris and Segel to sing "The Confrontation" from Les Misérables, a musical the costars are known to love. As the HIMYM cast looked on, Harris and Segel belted out the song with gusto, not even missing a beat as they sang different parts. Watch the video below, and then check out an adorable moment Harris shared with his kids  during the episode.
