I Think We're All Bozos on This Bus is the fourth comedy album made by the Firesign Theatre for Columbia Records, released in August 1971 on standard stereo vinyl LP, and Quadraphonic LP and 8-track tape. It was nominated for a Hugo Award for Best Dramatic Presentation in 1972 by the World Science Fiction Society.

The Firesign Theatre was an American surreal comedy troupe who first appeared on November 17, 1966, in a live performance on the Los Angeles radio program Radio Free Oz on station KPFK FM. They continued appearing on Radio Free Oz, which later moved to KRLA 1110 AM and then KMET FM, through February 1969. They produced fifteen record albums and a 45 rpm single under contract to Columbia Records from 1967 through 1976, and had three nationally syndicated radio programs: The Firesign Theatre Radio Hour Hour [sic] in 1970 on KPPC-FM; and Dear Friends (1970–1971) and Let's Eat! (1971–1972) on KPFK. They also appeared in front of live audiences, and continued to write, perform, and record on other labels, occasionally taking sabbaticals during which they wrote or performed solo or in smaller groups.
