WATCH: Flight of the Conchords return with a new hilarious song that’s really messed up

They're back on TV very soon too. Yes!

We've got a personal message to the Head of Programming at HBO, Mr Dave Random-Name*, after he decided to bring back Flight of the Conchords for a one-off TV special. "Oh, you're a legend Dave!" FYI, we've no idea if that's his name or not, but facts wouldn't make this gag work so well. https://www.youtube.com/watch?v=l4NKb9p9Qd8 Clip via Sam King Well, we're delighted to say that Jemaine Clement and Bret McKenzie are back and they even performed a new track, Father and Son, on The Late Show With Stephen Colbert. Good man Murray, finally getting the lads a decent booking! The group were promoting their upcoming HBO special Flight of the Conchords: Live at the London Apollo, which will air October 6th. The performance marked a return for the duo, whose HBO series ran for two seasons in 2008 and 2009. As for the new track, it's a bit warped  as a “a guy and his little guy” talk about why this boy's mother isn't around any longer. Spoiler alert: a guy named Trevor is partially to blame, but things just get weirder and weirder as things go on. Well, what else did you expect from the brilliant duo? Take a look. https://www.youtube.com/watch?time_continue=299&v=i8iK1rhfYpI Clip via The Late Show with Stephen Colbert
