Mondo Bizarro (a misspelled version of "Mondo Bizzarro", meaning "Weird World" in Italian) is the twelfth studio album by American punk rock band Ramones, released on September 1, 1992, by Radioactive Records. It is the first studio album to feature their new bassist, C.J. Ramone, who replaced original member Dee Dee Ramone (although he's still featured on this album and the band's subsequent albums as a songwriter). The album was re-released in the UK by the Captain Oi! record label on August 10, 2004, with the band's cover of the Spider-Man theme song included as a bonus track.
