"Have you ever noticed that when you start to enter something into the Google search bar, it produces a dropdown menu of "hints" based on the most common queries it has received? So, for example, if you type in "why," one of the hints is, "Why do cats purr?" If you type in "how many," you are prompted with "How many angels can dance on the head of a pin?"
When you follow up on these things, you find that most have either no answer or an unsatisfying answer. As a public service, I decided to answer them myself. Each of the questions below was suggested by Google.
Why do cats purr?
It is how they laugh at us."
