Hmm, $603,000 or $1?

Deal or No Deal: Biggest Bonehead Move @ Yahoo! Video

This guy had 3 cases left: one $1, and 2 $1,000,000 cases. He had a 1 in 3 chance in getting $1 by not taking the $603,000 offer. I'm telling you, there is NO WAY I would turn down $600k for the *chance* of a million. Greed or stupidity?
