Changing Number Terms

In a recent contest in The Washington Post, readers were asked to take an expression using a number, add or subtract one, and create a new definition:
The Year 2001 Problem: How to find jobs for all those programmers hired to solve the Year 2000 problem.
Catch-23: Complete the previous catch before proceeding to this step.
Fortune 501: Levi Strauss makes the list, but just by the seat of its pants.
Motel 5: If you're not there by midnight, they turn off the light.
Dressed to the Eights: Impeccably attired with white socks.
Six Brides for Seven Brothers: Someone's gonna get hurt!
Snow White and the Eight Dwarfs: The title, before they expelled Gassy.
Five Eyes: Other kids can be so cruel when you are Siamese twins, and one of you is wearing a monocle.
665: The mark on the forehead of Satan's slightly less evil brother, Ralph. 

Laws from the W-Men

Vuilleumier's Laws For Building Electronic Prototypes:
First Law - Any pre-cut equipment is too short; this is specially true of optic fiber cables with expensive connectors at both ends.
Second Law - If n electronic components are required, n-1 are available.
Third Law (also known as "Selective Gravitational Field") - Any tool escaping manipulator's hands will not necessarily follow Earth's gravitational field, but will land in the most unreachable location in the prototype, smashing on its way the most expensive component of the prototype; this will know only one exception if the tool is particularly heavy, in which case it will land on the manipulator's foot.
Fourth Law - When proteup first, thankfully leaving the fuses intact.
Fifth Law - Prototype npn blackboxes actually hold pnp transistors, and vice-versa.
Sixth Law - A quartz oscillator oscillates at a frequency off the rated one by a minimum of 25%, if it does oscillate at all.
Seventh Law - When the prototype has been fully assembled according to lab instructions, a minimum of 11 components are left.
Cutler Webster's Law: There are two sides to every argument, unless a person is personally involved, in which case there is only one.
Weiler's Law: Nothing is impossible for the man who doesn't have to do the work.
Weinberg's Corollary: An expert is a person who avoids the small errors while sweeping on to the grand fallacy.
Wethern's Law: Assumption is the mother of all screw-ups.
