Gordon Bennett
From Tardis Wiki, the free Doctor Who reference
"Gordon Bennett!" was an exclamation of shock, alarm or disbelief of which Ace was particularly fond. (TV: Dragonfire, The Happiness Patrol, The Greatest Show in the Galaxy, Battlefield; AUDIO: A Life of Crime, The Blood Furnace) One typical usage occurred when she had assumed that a Happiness Patrol member's gun was fake, only to watch it powerfully discharged in front of her. (TV: The Happiness Patrol)
