In Concepts of Mathematics, Ian Stewart, there is a math joke that goes like this...
An astronomer, a physicist, and a mathematician (it is said) were holidaying in Scotland. Glancing from a train window, they observed a black sheep in the middle of the field.
How interesting observed the astronomer, all Scottish sheep are black!
To which the physicist responded, No, no some Scottish sheep are black!
The mathematician gazed heavenward in supplication, and then intoned, In Scotland there exists at least one field, containing at least one sheep, at least one side of which is black.
Pick your role here. When I hear words like this can't be done, this has never been done, doing this is evil, doing this is a waste, this is always done, or any other absolute statement that contains never or always, in the absence of a domain, a context in that domain, tangible evidence that the statement is effective outside of a single person's observation, the insistence from the speaker that I've told you this many times over, some evidence from somewhere else, untested beyond opinion, or worse just stated because it sounds like a good idea - as Dilbert has mentioned in the past it looks like it's going to be a long day.
