In September 2019, Wer wird Millionär? celebrated its twentieth anniversary. In the special show, the lawyer Jan Stroh from Hamburg answered the final question and won one million euros. Afterward, the press reported how he had got there. For almost sixteen years he had replayed the show at home, at his own quiz desk, with all the sound effects. In his cellar he had his personal heißer Stuhl, hot seat. Over the years he built a large archive of questions, some from the show and some of his own. He told Bild he had not missed a single episode. His own summary: Richtig ‚durchgelernt‘ habe ich keine Fragen. He had not really crammed any questions.
