By totally miserable, do you mean miserable until the cameras stop rolling and he goes to shower, sleep and eat in a hotel? I can endure a lot of pain and hardship if I know that I only have to do it for five minutes and then I can go back to civilization for 10 hours. Les doesn't do stupid stunts and take unnecessary risks like Bear, but then again Les isn't a fraud. Also, if Bear lies about staying at hotels, do you really think that the stunts he pulls like drinking his own urine are actually true? It would be really easy to get a urine look-a-like and have him drink that. In fact, it would be par for the course.
