Ask former Celebrity Apprentice contestant Clint Black what current contestant John Rich is going through, and here's the answer ya get:

“John’s going through convulsions, fits, and giggles.”

“It’s such a grueling schedule, 18 hours a day, six days a week,” Clint tells CountryWeekly.com. “You come out of that with so much sleep deprivation.

“Plus you’ve been witness to some of the most abusive behavior known to man. Even when it’s not directed at yourself, it’s hard to be in a room with it. On that show, you get rewarded for (abusive behavior). It’s not about team building, it’s about team shredding.”

Clint says he’s caught a few episodes this season, and he called John “a real calm in the storm.”
