Die Ludolfs is a German docu-soap that followed the Ludolf brothers running a car scrapyard in Dernbach, first airing in the 2000s and building a cult following in Germany. Peter Ludolf, the eldest brother known for his encyclopedic knowledge of car parts and his warm manner, became the show's most quoted figure. Clips of his hearty, unmistakable laugh spread online as a standalone reaction sound, reused far beyond the series in memes, edits, and German soundboards.
