Watch: Which AM host bombs when doing stand-up comedy?

If you're tired of the joker in your office, just be glad you're not working in the AM office.

Ahead of the Best Foods Comedy Gala in Auckland on Friday September 9, host Rhys Mathewson dropped by AM to share some of his comedy wisdom with Ryan Bridge, Melissa Chan-Green and Bernadine Oliver-Kerby.

However, the hosts soon found themselves on the spot as they all attempted stand-up comedy.

Ryan Bridge revealed all three of them were "all freaking out" ahead of their comedy routines, as they attempted some original comedy material.

One of them bombed, one of them triumphed - and one of them stole some material from a website.

But who did what?

Watch the video above to see who wins.
