I once went through quite an experience. Used to work with a guy that was awarded a big prize in his field. I think one day he got tired of being treated as "some kind of genius", as he said. He started to discuss a topic one day, listening to my answers and questions back and forth. At the end the discussion hit a point where we could not go further. He then told me: "if you then submitted this as a proposal, were lucky enough to have it granted and just answered the last question you asked me with a simple experiment, you would receive the same prize as I did".
That guy was great.
