This one never made much sense to me, and now I know why. MTV edited the hell out of it.
The story:
A group of people sign up for a sociological research experiment: for the summer they are to live in a mock iron-age encampment that has been set up. With no preparation, no testing to make sure you are healthy, you just show up, sign up, change into a loincloth, hit the pub, and then make your way to the camp for the first time in the pitch black dark. Of course the last bit isn't as difficult as it might seem because the camp is IN THE MIDDLE OF CAMPUS.

Ok. Even with the hell not edited out of it, it still doesn't make much sense.
I'm clear on the concept - the humor lies in the way that all of the participants adapt to their surroundings. Some dive in so fast that they are talking like Thundarr the Barbarian before they finish getting their Armanis off. On the other side we get the ones who keep wearing aviator shades and sneaking martini breaks.

It is a lot better than it was, though.
