Bar Fight is a short Animation made by Christy Karacas and Stephen Warbrick.
A newcomer to a road house-type bar accidentally spills the beer of the guy sitting next to him, prompting the angry patron to throw him into the juke box. The impact causes the jukebox to switch from a mellow country song to an angry-sounding heavy metal song, which in turn prompts everyone in the bar to begin brutally attacking one another. The violence becomes progressively more brutal and surreal, ultimately involving firemen, space aliens, and ghosts. Finally, someone else is throw into the jukebox, switching it back to country music. The music causes everyone to lay down their arms, and the entire bar congregates to share a drink, including those killed during the mayhem.
