Cash Cab
If the contestant got to where they wanted to go without getting three strikes, they had a choice: they could leave the taxi and keep the money in their prize pool  or they could risk it on a "Video Bonus" question. If they decided to play the Video Bonus question, a video clip was played and they were asked a question based on the clip. If the contestant answered correctly, their prize pool was doubled. If they gave a wrong answer, they lost all of their prize.
