The Oscars had an all-time flub as presenters Faye Dunaway and Warren Beatty were handed a card naming the wrong winner for the best picture award.
Dunaway announced the winner as "La La Land" before "Moonlight" was revealed as the actual winner moments later.
PriceWaterHouseCoopers — the accounting firm responsible for the envelopes — took blame for the error.
Social media howled over the mistake. Here are some of the best responses to the error.
