Another way to avoid the bosses phone calls is to put a few typos in the company phone list. It gets rid of lots of annoying calls. Only the people you give your number to can reach you.

The nice thing about your patronising story is that it implies that you are yourself of such a superior intellect that you can set tests that will accurately identify genius - even if, of course, it is of a slightly inferior genius to your own.
Reminds me of the time the guys in my shop put a Christmas Tree flasher plug on the 74-year-old secretary's electronic typewriter ... it worked for a while, then it quit ... she called maintenance ... it started working again and she called them back to cancel ... then it quit working again ... it lasted all afternoon.
