Being out in the boonies, TV wise, right now, we can't see the neato stuff like that, so I can not reply re the knife, never seen it. I did see him on Jay Leno last night, and they showed a couple of clips from his show, both supposedly in the "desert." In thefirst clip he urinated on a cloth to wrap around hit head for cooling. Seems to me if he was that hard up he would probably have very little urine to produce. In the second clip he squeezed moisture out of elephant dung into his mouth (yuk). Jay commented that maybe he should just follow the elephants to their watering hole, that seemed to make a certain amount of sense to me...
