Trivia

 * Mark Feldman and Steve Striegel are the contestants in this season, who lost the biggest money in this season ($75,000).
 * On April 27, 2006, contestant Bob Juch had Jeff Gross (he in US and UK versions appeared as contestant) as Phone-a-Friend.
 * Dante Constable's on May 5, 2006 appearance was cut short by incorrectly answering a flawed $250,000 question. The producers later discovered that his answer was also correct, so he was awarded the $250,000 and invited back to the hot seat to try for $500,000.
