Go watch the 1955 movie The Dam Busters. The pilot's dog is a black lab called... Nigger.

Gibson had a dog called Nigger, a black Labrador which was the mascot of No. 617 Squadron. Gibson owned the dog when he was previously a member of 106 Squadron. Nigger often accompanied Gibson on training flights and was a great favourite of the members of both 106 and 617 Squadrons. He was noted for his liking of beer, which he drank from his own bowl in the Officers' Mess.

Nigger died on 16 May 1943, the day of the "Dam Busters" raid, when he was hit by a car. He was buried at midnight as Gibson was leading the raid. The dog's name was used as a single codeword whose transmission conveyed that the Möhne Dam had been breached. In the film, the dog was portrayed in several scenes; his name and the codeword were mentioned several times. Some of these scenes were sampled in the film Pink Floyd – The Wall (1982).

In 1999, British television network ITV broadcast a censored version of the film, removing all utterances of "Nigger". ITV blamed regional broadcaster London Weekend Television, which in turn alleged that a junior staff member had been responsible for the unauthorised cuts. When ITV again showed a censored version in June 2001, it was condemned by the Index on Censorship as "unnecessary and ridiculous" and because the edits introduced continuity errors. The British Channel 4 screened the censored American version in July 2007, in which the dialogue was dubbed so as to call the dog "Trigger", this screening took place just after the planned remake was announced. In September 2007, as part of the BBC Summer of British Film series, The Dam Busters was shown at selected cinemas across the UK in its uncut format. The original, uncensored, version was also shown on 1 and 5 January 2013, by Channel 5. It was the version, distributed by StudioCanal, containing shots of the bomber flying into a hill.

In 2020, Film 4 has broadcast an edited version, possibly re-dubbed in a few places, where the dog's name is removed, addressed as "old boy" or referred to as "my dog".
