This is a real show?
It is a real show and it actually is a great show. Sometimes people are just jerks. It is amazing what people will do without knowing a camera is on them.
I saw one episode back in 2008.
They were in France, and had a couple of actors portraying the "ugly Americans" in a patio restaurant; complete with "Bush 2008" T-shirts (never mind that he wasn't running in 2008). They were loud and obnoxious and were trying to get a rise out of people.
After the act was over, the host questioned some of the patrons in the restaurant. One French woman said something to the effect, after seeing the "Bush 2008" T-shirts, "It was like someone coming to a restaurant wearing a Hitler T-shirt".
The host let this pass, likely in full agreement with the woman that Bush (at the time, the current U.S. President) and Hitler were comparable.
It's not a great show.
It's a tool to enforce political correctness.
