The song "Werewolves of London" (1978) by Warren Zevon presents a surreal image of supernatural creature consuming tropical drink while maintaining perfect hair—absurdist juxtaposition of wild nature with refined civilization. The assertion that someone witnessed this exact scene, with added presence of another individual, inverted the song from imaginary to documentary observation. It positioned the song as historical record rather than satirical fiction.

Music history forums occasionally discussed whether Zevon's song referenced actual observed phenomena versus pure creative imagination. The assertion that someone could corroborate the song's narrative through eyewitness account—and that corroboration centered on hair maintenance rather than werewolf existence—inverted priorities entirely. The supernatural element became incidental; grooming became the remarkable feature.

The phrase entered music culture as darkly comedic assertion of documentary reality. Instead of treating Zevon's song as imaginative work, the assertion positioned it as journalistic record of observable phenomena. The werewolf became less remarkable than the presence of someone whose personal grooming transcended werewolf status.

The assertion transformed the entire song into evidence rather than fiction—a historical account waiting for corroboration. The pina colada and werewolf became less surreal image and more straightforward description of events that someone could verify through eyewitness testimony, providing more details than Zevon himself included.
