After seeing an AWFUL promofor this show on TV I had to look it up on the Discovery Channel website: 

Going Tribal follows former Royal Marine and expedition leader Bruce Parry as he tests the physical limits of living with ancient tribes in some of the world's most remote areas. Parry sheds social trappings (and sometimes his Western clothes) by living alongside people from the virtually unexplored areas of the Himalayas, Ethiopia, West Papua, Gabon and Mongolia. To the degree possible, while spending a month immersed in each society, Parry also tries to adopt the methods and practices of his hosts. Parry enthusiastically embraces jungle hunting and the rituals of the warrior, being taught by strangers how to survive using bows, arrows, blowpipes, dogs, spears, traps, snares and clubs. He must cook and eat his catch using traditional methods such as hot stones, waxy leaves and bamboo pots. Parry is accompanied by a translator, but learns the basics of tribal language. The series is accompanied by subtitles. Viewers hear unique languages and watch the sometimes-graphic practices of living and surviving in the jungle among some of the world's disappearing cultures. Going Tribal premieres Tuesday, Aug. 9, at 10 p.m. ET/PT, and will continue to air Tuesdays at 10 p.m. ET/PT for the next five weeks. Going Tribal is produced for Discovery Channel by the BBC.

This was a great response to the show from someone who posted on the show's forum:

From the looks of the "Going Tribal" website, this may well be the most bigoted, condescending, racist show on television. The premise seems to be: brave white man meets dark wild savages, and spears fly! I'm glad that I don't get the Discovery Channel on my cable system, or I might feel compelled to watch this in order to see just how horrible it is. Kind of like the stairway in the building where I work - there is a dead bird that crashed into the window by the stairwell, and now tweety is decomposing on a ledge, and every time I go to another floor my eyes are drawn to the gory spectacle. I often respect the programs the Discovery Channel airs, but this looks to be the lowest of the low. I write this as an anthropologist who has lived and worked in a remote part of Africa for many years. I was most recently at my home there one month ago. The sensationalistic promos on this website give the impression of primitives as they only exist in Hollywood's imagination - and I fear that the programs themselves will be carefully edited to fulfill that imaginary view of distant peoples.
