This famous Kiwi has just appeared on a major US television show

A popular Kiwi has appeared on the famous US television show James Corden's 'The Late Late Show'.

But in a bit of a turn of events, it turns out Radio Hauraki host Leigh Hart didn't even know it.

Hart popped up this week when Corden played the game 'None of the Above,' which sees Corden play an old video clip before quizzing an audience member.

Somehow Corden had selected a clip featuring the Kiwi comedian in a fitness segment from Late Night Big Breakfast, which used to screen on TVNZ.

After playing the clip, Corden asked the contestant what the interview was about, giving him four options including: A) A fire alarm going off B) Someone dropping a heavy weight C) Realising they are brothers or D) None of the above.

Of course, the answer is D) None of the above.

The clip has since gone viral across the globe as a viral 'gym fail' video.
