The Academy made a brief snafu during "The Cove" team's speech for Best Documentary. As the film's star, Ric O'Barry, held up a sign with an activist statement on it, the Academy panicked, abruptly cuing the music and cutting away right as the film's director, Louie Psihoyos, was about to make his speech:

The sign that scared the Academy said "Text Dolphin to 44144." Sending the text will sign you up to get messages about how to help end the dolphin hunt in Taiji, Japan. How on earth is this offensive? Were they serving dolphin meat at the award buffet?
