NBC's The Island clip: We can't describe how gross this is

They never show this kind of stuff on Survivor.

On the next episode of NBC’s The Island—the Bear Grylls-hosted adventure series about a bunch of men who are left to fend for themselves on a deserted island—one of the participants battles an epic case of constipation.

Trey Williams, a 31-year-old digital marketing manager from Kansas City, Mo, is so traumatized by his inability to go No. 2 that it “petrifies me every time I hear that grumble” from his bowels.

But you won’t believe how he finds relief. All we can say is, thank goodness Grylls and his people thought to include a trauma surgeon in the cast.

“You haven’t truly lived until you’ve spent two and a half hours digging four to five pounds of coconut, bark and crab shell out of your own butt,” admits Williams.
