GM's defective deathtrap commercial
When you're a car manufacturer, the last words you want associated with your product are words like deathtrap, Hidenburg, catastrophically flawed, and the like. In fact, these words would do so much damage that you may even create a memo with a list of these words for all employees to be aware of, so they are never, ever used in the same sentence as your brand. Except, in today's world, such memos often make their way into the hands of the public... or a celebrity talk show host, who then turns them into a hilarious parody ad and air them on their show and their YouTube Channel. Bravo John Oliver, braaaavo.
