As John Oliver is filling in for Jon Stewart over at The Daily Show for the summer, Oliver is deadly terrified of what may happen and thus looking for any advice.

In a related story, Brian Williams made a sincere gesture to Jon Stewart last night on The Daily Show to not let this “Oliver Twist” guy take over at the top and end of the interview.
