Scramalot
From Muppet Wiki
Scramalot is a Sesame Street parody of the Monty Python musical "Spamalot."
In the sketch a cast of Grouches (performed by David Rudman, Leslie Carrara, Matt Vogel, and Fran Brill) put on their rendition of the musical "Scramalot." However, the musical numbers are frequently interrupted by the Grouches' inability to rhyme.
