Andy Grove's biography tells the story how he had Bill Gates over for dinner to discuss the relationship between Intel and Microsoft. Upon hearing one if Andy's proposals, an excitable Gates said that it would "be actionable" (meaning the company could act on it). Andy misunderstood, and stood up from the table and angrily pointed at Bill and shouted "are you threatening to sue me?!". The meeting went badly from that point, and presaged a bad relationship between the companies for years to come.
