Watch: Patricia Arquette’s hilarious story of realizing her Oscar nom was real

Patricia Arquette may have won a Lead Actress Emmy for her work on “Medium” in the mid 2000s, but that doesn't mean the thrill of an Oscar nomination for her role in “Boyhood” isn't an entirely new thrill for her.

At Monday's Oscar luncheon at the Beverly Hilton, Arquette opened up about the panic and jubilation of realizing — finally — that her nomination had really happened. Wonder if her (inevitable) win will be just as madness-inducing.
