Can you hear me now?

Remember that Verizon commercial where some guy "tests" his cell signal in swamps and deep in the woods and in the middle of rush hour? The "can you hear me now?" guy is based on the real thing. Verizon engineers traverse the country testing signal but they aren't using the phrase "Can you hear me now?" They're using a set of special sentences written in a secret basement lab at Harvard during WWII. More about these Harvard Sentences in the podcast and British Justice Minister Michael Gove lays down the grammar laws for his staff. Gove's not-so-secret list of grammar no-nos.
