"Mighty Science Theater" is an instrumental theme played over the end credits of almost every episode of Mystery Science Theater 3000. It is a slowed down, abbreviated version of the "MST3K Love Theme" done in a more majestic style. It has been part of the show since Season 1.
Once in a while, a gag from the last host segment in the show extends into the credit sequence. This usually results in sound effects or voices playing on top of "Mighty Science Theater" (such as Pearl snoring in the end credits of Experiment #805). On other occasions, "Mighty Science Theater" is not played at all and is replaced with an instrumental or part of a song sung earlier in the episode, such as Experiment #424, where the chilling "Torgo Theme" plays.
For the revival, the theme was reworked into a full orchestral version recorded with live instruments and it typically plays after several MST3K song covers by The Skeleton Crew.
