<P> Should the passenger (s) reach the destination without striking out, Bailey / Melewski offers a choice: the option of leaving the cab and keeping the prize money that they have won, or they can stay and try to double their money by risking it all on a Video Bonus question . Bailey / Melewski plays a video clip and asks the contestant (s) a single question based on its content . If the question is answered correctly, the contestant (s) win double what they have earned so far, but if they are wrong, they lose all of their money "at the very last moment", as Bailey says, and "leave with nothing but a cab ride". </P> <P> Beginning in Season 4, this rarely occurring part of the show happens when randomly selected passengers are able to win double the amount of money of a normal game . The first four questions are worth $100, the second four are worth $200 and the rest until the end of the game are worth $400 . The "Red Light Challenge" is worth $500 . </P> <P> The current record of $6,200 won on one ride is held by Sam Meyer (riding solo, on a Double Ride, taking and winning the Double - or - Nothing Video Bonus question) on the episode that aired May 18, 2009 . This topped the old record held by contestants Sean Devney and Steve Irolla, two New York City tour guides who won $4,100 after answering the "Video Bonus" question correctly . They reached their final destination with two strikes (both on $200 questions). </P> <P> One episode of the program was a special celebrity edition, featuring actor Thomas Haden Church of Spider - Man 3, NHL players Jed Ortmeyer and Ryan Hollweg of the New York Rangers and journalist Harry Smith, formerly of CBS' The Early Show . All played for a charity of their choice, and Discovery Channel matched the contestants' winnings . Another episode was a special in which the passengers were asked questions relating to the 2008 film Frost / Nixon . In this episode, the host of Cash Cab: Canada, Adam Growe, was driving the cab instead of Ben Bailey . </P>
