Jon Stewart’s directorial debut with Rosewater opens today and, as you could imagine, he used last night’s episode of The Daily Show to promote it.

With that being the case, Stewart felt it would be tasteless to be also promoting while hosting. So, he was just in luck that one John Oliver, who has had filled in for him before, had just wrapped season one of Last Week Tonight at HBO and was free to fill in. 

Watch Oliver sit once more at The Daily Show desk right here.
