Arthur Read, the spectacular bespectacled aardvark, stars in this children's series about growing up. Typical childhood problems such as bratty siblings, schoolyard bullies and classroom cliques are addressed by this popular program which has been running for 20 years on PBS. Developed from Marc Brown's beloved books, Arthur reminds us all of how it feels to be 8 years old. Just like your average kid, Arthur overcomes the dreaded obstacles of third-grade life, such as his tough teacher Mr. Ratburn, bullies, and mountains of homework. At home, Arthur must also face the pint-sized terror known as his sister Dora Winifred, or D.W. for short. Everything between these two is a struggle; such as who gets control of the television remote, or who can play their Crazy Bus CD. Arthur often relies on his best friend Buster Baxter, a rabbit.
