Being a PCV means you assume the role of 'expert' lots of times when you shouldn't. However, sometimes, you need to just hold off answering until you have access to Google. And let me just say, I don't know what I would do without Google! My two most recent Google searches: "what are penguin arms called" and "parts of an ostrich". For those who care, penguins wings are called flippers and ostrich arms are classified as wings.
