Neil Patrick Harris and Jason Segel sing "The Confrontation" from Les Miz on "At The Actor's Studio"

What happens when you ask two TV actors to sing a duet – on the fly LIVE – that has nothing to do with their TV series?

Neil Patrick Harris and Jason Segel of How I Met Your Mother Sing “Confrontation” from Les Miserables (Inside the Actors Studio (2014)

Apparently, Neil and Jason sing this together onset as an ongoing joke. I think the first time they did it on TV was 8 years ago on the now-defunct Megan Mullally Show.
