An Ice Cream Show (PBS, 9-10 p.m.): This documentary, narrated by Rick Sebak of Pittsburgh's WQED, serves up a double dip of history and trivia on America's favorite summertime treat. (For instance, Americans eat enough ice cream every year to fill the Grand Canyon.)
The show travels from Penn State, home of what has to be the sweetest college course around, to Hawaii, where they serve red beans with their shave ices (sno-cones to us mainlanders). Other ice cream hot spots include a Florida drive-through stand shaped like a soft-serve cone, and Robin Rose Ice Cream in Venice, Calif., which has a traffic school in back so you can sample rose petal ice cream while brushing up on the rules of the road.
