The line comes from Wallace, the cheese-loving inventor voiced by Peter Sallis, in the Wallace and Gromit short film A Matter of Loaf and Death, released in 2008. In the film Wallace finds himself in a perilous situation involving a bomb, and his blunt northern announcement turns the threat into comedy rather than suspense. Fans later clipped the moment for soundboards and short videos, where its short length and instantly clear panic made it easy to reuse. It endures because the phrase is memorable, quotable and immediately signals exaggerated alarm without needing any context.
About this sound
He shouts that he has a bomb in his pants in Wallace and Gromit: A Matter of Loaf and Death, a comic quote used for sudden panic and fake danger moments.
This short clip captures Wallace in panic as he blurts out that a bomb is hidden in his trousers, his voice rising in frantic, breathless alarm while the joke lands because the danger is both urgent and absurd. The delivery is fast, high-pitched and squeaky, with the northern English phrasing making it sound even more comically desperate. Listeners picture a character who has realised too late that something explosive is far too close for comfort. It works as a punchline because the terror is genuine but the situation is ridiculous, turning a moment of supposed peril into pure slapstick and leaving the audience laughing at Wallace's helpless, wide-eyed worry.
