The 1960s song "The Little Old Lady from Pasadena" parodies a popular Southern California image of Pasadena as home to a large population of aged eccentrics. In the song, Jan and Dean sing of an elderly lady who drives a powerful "Super Stock Dodge" muscle car and is "the terror of Colorado Boulevard." The Dead Kennedys paid a tribute to this archetypal song in the track "Buzzbomb From Pasadena" in the album Give Me Convenience or Give Me Death. Pasadena was also the location of the 2012 film Project X.
