Wer wird Millionär is the German version of Who Wants to Be a Millionaire, airing on RTL since 1999 with host Günther Jauch. The Telefonjoker, literally phone joker, is its version of the Phone a Friend lifeline, letting contestants call someone for help on a tough question within a strict time limit. The ringing and suspense cue became instantly recognisable to German TV audiences. Online, creators reuse it far beyond quiz shows, dropping it into videos whenever someone needs backup, stalls for time, or pretends a trivial choice is a million euro decision.
