Spurlock says he didn't lie on his work applications. He admitted to being a college graduate but told employers that he was the subject of a documentary, which explained why cameras were following him.

"You have to wonder what our lives would have been like if we weren't college graduates or if we were a different race," he says. "It opened my eyes to what comes into play in this situation."

They had $35 in their budget each week for food. "That's eating cheaply. It's vegetables and rice and beans," he says. "We didn't buy one thing in a box."

Jamieson was inspired to write a book on how to eat cheaply and healthy.

The stress of the situation also played upon his relationship with Jamieson. Spurlock cites a statistic that couples making less than $25,000 are twice as likely to get divorced than families making $50,000.

"You start to see the stress and strain. You are physically and emotionally spent. We bickered about silly things, like what happened at work," Spurlock says. "We were there for a month. You have to wonder what it is like for people who live in this every day."

And what did Spurlock and Jamieson do when the 30 days was up? "We went out to dinner," he says. "It was fantastic."
