Well, this is just delightful. On the "How I Met Your Mother" episode of "Inside The Actors Studio," an audience member asked Neil Patrick Harris and Jason Segel to sing "Confrontation" from "Les Miserables," since the show is returning to Broadway.
"You haven't sung that in a long time!" Alyson Hannigan said. But, without hesitation the guys launched into an A+ rendition. Seriously, it's great. Watch the whole clip above.
The "How I Met Your Mother" series finale airs March 31 at 8 p.m. EDT on CBS.
