Appropriate to remember the original use for this phrase was to describe him stealing ideas from engineers with no credit in a psychotic fashion and make scheduling realistic release dates impossible:
> he's really funny about ideas. If you tell him a new idea, he'll usually tell you that he thinks it's stupid. But then, if he actually likes it, exactly one week later, he'll come back to you and propose your idea to you, as if he thought of it."
And
> He can convince anyone of practically anything. It wears off when he's not around, but it makes it hard to have realistic schedules.
