The line comes from Crocodile Dundee, the 1986 Australian comedy film starring Paul Hogan as Mick Dundee, an outback adventurer visiting New York City. In the scene, a mugger threatens him with a small knife, and Dundee answers by drawing a far larger Bowie knife, turning a tense confrontation into a joke about scale. The exchange became one of the film's most quoted moments and later spread through reaction videos, edits and soundboards, where it still works because the setup and payoff are instantly recognisable even without seeing the film.
