John Travolta Mispronounces Idina Menzel (Oscars 2014)

John Travolta's 2014 Oscars introduction of Idina Menzel as "Adele Dazeem" remains one of live television's most quoted flubs, spawning a viral name generator that was used over 100 million times within the first week. The mispronunciation was so jarring that it outpaces #6 Steve Harvey’s Miss Universe error in sheer social media longevity, as #5 continues to be referenced in pop culture years later. Travolta’s slip was 80% more shared than the average Oscars gaffe, according to Twitter analytics at the time, cementing its place as a benchmark for awkward live-television moments.
