The Firesign Theatre is an American comedy troupe that employs a stream of consciousness style that links direct references to movies, radio, TV, political figures, and other cultural sources, intermingled with sound effects and bits of music. The stories are often interrupted by commercials satirizing real products. While their stream of consciousness style has the feel of improvisational comedy, most of it actually is tightly scripted and memorized.
