THE DAILY SHOW WITH JON STEWART
Comedy Central, 11:00 p.m. ET
Here’s a test of the interviewing abilities of Stewart’s summer substitute host, John Oliver. Tonight his guest is Josh Fox, the filmmaker whose documentary, Gasland Part II, provides for a lot of opportunities to make serious as well as comic points. And Fox is just off an appearance on HBO’s Real Time with Bill Maher, where he held his own, and more, against an angry assault from one of the show’s conservative guests.
