While Brett is watching Werewolf of London (mistakenly confused for The Wolfman) Brett and Ted discuss werewolves and their existence with Ted stating that it doesn't take a full moon to start the transformation and saying that he has "been acquainted with a few in his time" and Brett stating that werewolves don't exist.
Wolfman Jack frequently referenced the phrase and there is a sound clip of him using the line within the song "Clap for the Wolfman" by The Guess Who.
