From Wikipeida:

In 1997, Entertainment Weekly ranked the Firesign Theatre among the “Thirty Greatest Comedy Acts of All Time”. Their 1970 album Don’t Crush That Dwarf, Hand Me the Pliers was nominated in 1971 for the Hugo Award for Best Dramatic Presentation by the World Science Fiction Society, and their next album I Think We’re All Bozos on This Bus received the same nomination in 1972. Later, they received nominations for the Grammy Award for Best Comedy Album for three of their albums: The Three Faces of Al (1984), Give Me Immortality or Give Me Death (1998), and Bride of Firesign (2001). In 2005, the US Library of Congress added Don’t Crush That Dwarf to the National Recording Registry and called the group “the Beatles of comedy.”
