That was pretty wild!
There's at least some precedent for the 'La La Land'-'Moonlight' snafu that has gone down as one of the most shocking moments in Academy Awards history.
It's safe to say that the snafu will go down as one of the most shocking moments in Academy Awards history, but a presenter receiving the incorrect envelope is not a completely unprecedented occurrence at the show -- it's happened before!
The year was 1964, and Sammy Davis Jr. was to read the winner for the Adapted Music Score category, only to unwittingly declare John Addison (Tom Jones) the winner.
It's not totally the same. While Addison did win that night, it was in the Original Music Score category.
"They gave me the wrong envelope?" Davis asked, before everything was cleared up, and Andre Previn was announced as the winner for Irma la Douce.
"Wait'll the NAACP hears about this!" Davis joked after the incident.
Meanwhile, Oscars host Jimmy Kimmel made light of Sunday night's mistake, jokingly referring to it as one of his signature pranks.
