A law invented by Marc of The Templin Institute and introduced in the video "The Idiotic Strategy That Always Works (But Shouldn't!)":
"Dumb ideas are implemented all the time often with cataclysmic results. But they're implemented in the first place because there was a legitimate expectation of a positive outcome; these ideas fall within the "Zone of Believability." However some ideas are so clearly bad and consequences so obvious that no sensible person would ever consider them; such ideas cross the threshold into the "Zone of Ridiculousness" and no explanation can ever justify such an idea's inherit preposterousness."
Essentially this law dictates that are 2 categories that a dumb idea fit under: Believable (Reasonable chance of a positive outcome) and Ridiculous (Very high chance of 1 or more bad outcomes), and that any idea that fits under the latter category should be flat-out rejected.

Executive Officer: Sir, there's so much wrong with that plan that it breaks Marc's First Law; I can't even list out every possible way that it could fail!

Pink laws are paper laws or rules that aren't generally or sufficiently practiced or enforced but are used or can be used arbitrarily on people or to selectively target people by corrupt authorities or others.
Having to get a business license when you're starting out a business in this city is a pink law man, I'm telling you people run businesses here without licenses, it's normal over here. Sure some get caught but it's normal to run a small business here without a license.

Many an addicted gamer believes in Murphy's Law of Gambling, even though it is indeed :"all chance" and thus seldom actually works out that way.
