Robert Downey Jr.'s irreverent speech for his first Oscar: "I thank my veterinarian, I mean, my wife". The actor began his acceptance speech by dedicating the award to his horrible childhood.

"I would like to thank my terrible childhood and the Academy, in that order," he said. It was the third Oscar nomination for a veteran actor known as one of Hollywood's most versatile performers, but who until Sunday had never won an Oscar. Oppenheimer sweeps the Oscars for best film, director and actors in a year full of cinema.
