I was watching this program called In World's Lost Tribes:New Adventures of Mark and Olly on Discovery. It's about these two white guys living amongst the Mek Tribe, a primitive tribe that had pretty much preserved their way of living for thousands of years in the deep jungles of Papua New Guinea for four months.
While I think it's cool that there is some mysteries left in the world; I don't quite understand their choice of clothes or rather lack of it. Here's is why.

Ta-DAH! Meet the Mek Tribe. The men walk around in the nude with only this pipe-like object that covers their penises - it's called a penis gourd. I am not ethnocentric but I seriously find this an inconvenience. Since life in the jungle is so complex; almost like a field of bobby traps, doesn't the penis gourd like get in the way a lot? Like when you're climbing trees - how about risking your gourd to get stuck between tree branches? I can think of a million scenarios getting caught in awkward situations.
True to societal order, if you're someone special like the village headman, you get to adorned your gourd with feathers and miscellaneous accessories. I wonder how it stays in place, they surely don't walk around with permenant hard-ons right. I guess, I will be waiting till next episode to see that because one of the white dudes will get to wear one.
