Sid the Science Kid

A youngster named Sid, who aspires to a career in stand-up comedy, pitches a morning monologue to his stuffed animals that hinges on a burning question (such as "Why do bananas get brown spots?"), then spends the rest of the day searching for the answer in this hybrid combination of animation and puppetry from The Jim Henson Co., in its first PBS project since "Sesame Street."
