The line comes from Sledge Hammer, the American action comedy series that ran from 1986 to 1988 and parodied tough cop films. Inspector Sledge Hammer, played by David Rasche, was famous for the catchphrase Trust me, I know what I am doing, usually said before causing more damage. In the German dub the opening became Vertrauen Sie mir, and the shortened clip circulated online as a retro reaction sound. Its cult following keeps the quote alive in edits where overconfidence is the joke.
