In this episode of Last Week Tonight with John Oliver, the focus is on predatory churches and televangelists, and how the U.S. tax law allows them to get away with almost anything. Oliver discusses how these institutions are taking advantage of people's faith for abhorrent monetary gain, and he even goes as far as founding a "church" as an exercise in exposing how ridiculous this whole scheme is.

However, as one of the comments notes, this episode lacked the usual laughs, learning, and path to improvement that Oliver is known for. Though it is difficult to come up with a concrete step to be taken to try to improve the situation due to the First Amendment, this episode could have had a more constructive approach. Nonetheless, it is still a good reminder of how important it is to be aware of the underhanded tactics of some institutions.

On the latest episode of Last Week Tonight with John Oliver, the show focused on the issue of government surveillance. John Oliver sat down with Edward Snowden to discuss the National Security Agency (NSA) and the balance between privacy and security. While the show often provides a humorous take on current events, this episode was no exception. The show discussed the importance of government checks on surveillance programs and how the lack of these checks can be concerning.

Unfortunately, the show took a misstep when they asked Edward Snowden about his views on dick pics. Snowden seemed taken aback by the question and it fell flat, as it was neither educational nor entertaining. It was clear that he was not prepared for this type of humor and the segment should have gone in a different direction. Despite this misstep, Last Week Tonight provided an insightful and humorous look into the issues surrounding government surveillance.
