Well, we don't have to speculate as to whether there is some sort of emotional taint on Zitron's thinking; it's shot through. But again, that does nothing to damage or offset _the argument_, which is available for your inspection and consideration, and you, as a thinking person, are handily capable of vetting. :) There is no need to use a heuristic; you have the thing itself.
The square of the hypotenuse — you multiply it by its bleedin' self — is LITERALLY equal to the sum of the squares of the other two sides. Again. Multiply each of the other sides BY THEMSELVES, and then add them together. It's that bleedin' simple Jim Cramer could do it. That number is the same as the square of the hypotenuse, no matter what idiot CEOs think.
