Comedienne Carol Burnett has signed on to guest star in at least one episode of Glee, which will air in October or November. Rumor has it that Burnett - a comedy legend well-known for her work on the small screen - will be playing Sue Sylvester’s mother.

This has got to be one of the greatest casting decisions ever. Carol has won six Emmy awards over the course of her career, and she’ll definitely be a great complement to Jane Lynch’s acerbic character.
