Laura Trevelyan's "Quick! Reach For The Mute Button!" voice is part of The Unholy Three of Miz Trevelyan, Donald Trump, and the ESPN sports announcer Dick ("DOOOOOOOK!") Vitale.
Like unhappy marriages, these horrifically unbearable voices are each unbearable in their own distinct ways. Trump's is the voice of the schoolyard bully, Vitale's the voice of the schoolyard idiot, and Trevelyan's is the voice of Marge Simpson in the British version of the American cartoon show. What Boris Johnson is to world leaders, Miz Trevelyan is to accents. She may be the sweetest person in the world, but she's got about as much business being a news anchor as------Marge Simpson.
