This quote sums it up pretty well.
“Frankly, I don’t understand the need for it,” wrote Adam Richman, host of the Travel Channel’s Man Versus Food. “Have you ever tried going to the bathroom the day after eating half a dozen Habaneros? Half the food I eat feels horrible coming out. Doesn’t mean it’s bad food, just means that the experience is all in the eating. If I cared about how it came out, I’d be on a diet of oatmeal, yogurt and branflakes."
Ironically, when it comes to what the food feels like coming out, I think they'll find most TV viewers don't give a s**t.
