Jon Stewart asked you to sit in as host this summer while he directs a film. Any hesitation?

I’d do anything for him, whether it’s hosting the show or helping him move. This show changed my life. I moved from the U.K. and met my wife [Kate] because of it.

Any nerves?

It’s terrifying, but I know how the engine works. Now I get to drive.

So who’s the better “John”?

He has ownership of that name in the office. They all call me Oliver.

Do you get your name back now?

I’ll go bigger. Like Great Leader, Dear Leader, Oh Powerful One. I’ve not decided yet.
