A two-hour tapestry of cartoon clips accents "What's Up Doc?: A Salute to Bugs Bunny" on TNT Monday at 8 p.m.

The looney and creative atmosphere at Warner Bros., the studio that created and developed this "wascally wabbit," becomes apparent during interviews with four directors who appear in this celebration of Bugs Bunny and his roots.

Ten original full-length cartoons that best represent the various stages of the character's evolution are included. So are a look at some of the artists who were responsible. But the special comes to life through the work of Mel Blanc, the man of a thousand voices, who not only supplied the voice of Bugs but often did the voices of all the other characters as well.

In his 60-year career, Blanc provided the voices for nearly 3,000 animated cartoons, including Bugs Bunny, Porky Pig, Daffy Duck, Sylvester the Cat and Tweety Pie; Barney Rubble and Dino the Dinosaur in "The Flintstones," and various roles in "The Jetsons." In "Gorilla My Dreams," included in this special to showcase the many voices of Blanc, he not only does Bugs, he is also the voice of an entire jungle. Blanc died last year.

Producer/director/co-writer Carl Lindahl fully researched his subject. Rare interviews with creators and directors Tex Avery, Chuck Jones, Friz Freleng and Bob Clampett are informative and substantiate the facts. But most of all they help bring out "the fun in the material," Lindahl says. His co-writer was Bob Waldman. Encores: Saturday at 8 p.m. Sunday, Nov. 18, at 10 a.m., and noon on Thanksgiving Day.

Monday on The Discovery Channel at 9 p.m. the premiere of "A Teacher's Story," a three-part series about the methods of three unique teachers who made an impact on education worldwide. The first one-hour episode, "Socrates for Six-Year-Olds," focuses on American Matthew Lipman and his method of teaching critical thinking.

The series marks the first prime-time presentation of "Assignment Discovery." Next Monday's episode, "The Butterflies of Zagorsk," was filmed at Lev Vygotsky's Children's Home for Deaf-Blind in the Soviet Union, where youngsters learn to conquer their world of silent darkness. The final show, "Out of the Wilderness," takes place in Israel and explores Reuven Feuerstein's methods of testing children's ability to learn, rather than to rely on what they already know.

Each show repeats on Fridays at midnight and Saturdays at 3 p.m.

Saturday on C-Span at 11 a.m. "News in the Nineties" is the topic of an International Women's Media Foundation gathering. Katharine Graham, chairman of the board of The Washington Post Company, will deliver the keynote address.
