Discovery (April 30, 5 p.m. ET)
A new season kicks off for the only quiz show I would ever describe as adorable: It’s conducted inside a taxi as it cruises up and down the busy streets of Manhattan. Unsuspecting passengers hop into the cab and shout their destination. At that point colored lights flash in the ceiling and host-driver Ben Bailey, as easygoing as Broadway is long, explains the show’s setup. He asks the questions, which are rewarded with cash. When a question’s too challenging, you can actually have him pull over so you can ask a passerby for help. Everyone onboard seems to be tickled to have an ordinary cab ride (which in New York City usually ends with sullen thoughts of how much to tip) transformed by such a silly shot of adrenaline. If only there were a Cash Elevator. All hail Cash Cab!
