Long ago when I worked as a production cost estimator for a windshield factory, some exec got one of his relatives, a really, really obnoxious know-it-all college kid a part time job in the same dingy office.

One day he came in to work after his morning classes, and in attempt to make be look stupid he asked me, "What does 'OBAFGKMN' stand for. I replied, "Sounds like the stelar sequence to me, but there's also an alternate 'OBAFGKMRN'".

The stunned look on his face was precious, and he stuttered, "How did you know that?". I told him, "I know a lot of things, and probably a lot of things you don't know".

Proof of this was a few days later when the corp. controller retired and was not replaced. Kid settled right into the vacant office, and I said not a word. A couple of days later management roughly rousted him out and moved my stuff in. Boy was he pissed, "You knew about this, why didn't you tell me?".
