Now I'm just feeling more stupid! What's a "ferryman's oar"? (Assuming it isn't literally an oar used by a ferryman).

It's a story, the ferryman has the oar, he stops being the ferryman without it, the next guy having it is the new ferryman. So you just pass it on. It's a task you can never finish but only pass on.

Thank you so much!
