You can probably guess, just from the title, which film featured this song.  Written and performed by The Dickies, Killer Klowns played over the end credits of Killer Klowns From Outer Space.  The video features scenes from that film, mixed in with the band performing the song behind bars.

The video was directed by Chuck Cirino, who also did the sound design for the film.  Killer Klowns From Outer Space has gone on to become a huge cult film, one that is discovered by new fans everyday.  Just as the film endures, so do The Dickies.  In some form or another, the Dickies have been together since 1977.

Enjoy!
