Cattle prod
From Tardis Wiki, the free Doctor Who reference
A cattle prod was a device used by the humans on the Soviet submarine, the Firebird, against polar bears. In 1983, Lieutenant Stepashin attacked Grand Marshall Skaldak from behind with the Firebird's cattle prod. This knocked out Skaldak. (TV: Cold War)
Albertine used a cattle prod to protect Toby the Sapient Pig. On one occasion, she used it to render the Sixth Doctor, Peri Brown, and Alice Bultitude unconscious. (AUDIO: Year of the Pig)
