Several weeks back I stumbled upon this show called Cash Cab airing on the Discovery Channel. The premise is that unsuspecting riders are picked up by a cab that will give them a ride to their destination and they then become instant contestants of this quirky game show. The contestants earn money for each correct answer and a strike for each incorrect. Three strike and you're out of the cab wether or not you've reached you destination.
This show is like " who wants to be a millionaire" but on wheels. You get 2 opportunities to ask for help. One of them is a mobile call to family or friends to help you with the correct answer. The other one is a shout out. It's where the cab pulls over and the contestant can ask for help from anyone on the street. See the similarities. The major difference being that on Cash Cab you can win a couple hundred or at most a couple thousand.
If you manage to reach your destination and have accumulated some money you are then given the option to double you earnings by answering correctly a question pertaing to a video that you view in the cab. The decision is entirely up to the contestant.
If you have'nt already seen this show you have to check it out on the Discovery Channel. See if you are more knowledgeable than the contestants.
