Creag an tuire

! was a battle cry used by Jamie McCrimmon, particularly when facing adversaries in his native Scotland. (TV: The War Games) However, he sometimes yelled it out when coming up against a particularly difficult opponent, regardless of the location. (AUDIO: The Black Hole, TV: The Enemy of the World)

Behind the scenes
The phrase is often misunderstood by viewers and professional closed captioners alike. In the captions to The Enemy of the World, the phrase is rendered "Brigadoon!" Some fans have believed the phrase to be "Creag an tuirc!" — but that's the battle cry of another clan.
