I agree Pete, it is irresponsible to present it as an informative show about survival.  
The lesson to be learned is: Don't believe everything you see on TV.  Especially if it involves pissing on your own head.  
I've only watched the clips on the Discovery site, but I already have two mental scars just from that.  It seems like many of the "survival" skills involve doing something "gross".  A few children may consider that to have entertainment value, but that's about it.  
All TV programs should be required to display a disclaimer: "WARNING - The following show may insult your intelligence."
