This is just a collection of social Laws that I find quite amusing.

Brooks' law — Adding manpower to a late software project makes it later. Named after Fred Brooks, author of the well known book on Project Management, The Mythical Man-Month.
Clarke's three laws — Formulated by Arthur C. Clarke. Several corollaries to these laws have also been proposed.
First law: When a distinguished but elderly scientist states that something is possible, he is almost certainly right. When he states that something is impossible, he is very probably wrong.
Second law: The only way of discovering the limits of the possible is to venture a little way past them into the impossible.
Third law: Any sufficiently advanced technology is indistinguishable from magic.
Conway's Law — Any piece of software reflects the organizational structure that produced it. Named for Melvin Conway.

Goodhart's law — When a measure becomes a target, it ceases to be a good measure.
Hanlon's razor - "Never attribute to malice that which can be adequately explained by stupidity." or "Do not invoke conspiracy as explanation when ignorance and incompetence will suffice, as conspiracy implies intelligence."

Littlewood's law — States that individuals can expect miracles to happen to them, at the rate of about one per month. Coined by Professor J E Littlewood, (1885–1977)
Moynihan's law — "The amount of violations of human rights in a country is always an inverse function of the amount of complaints about human rights violations heard from there. The greater the number of complaints being aired, the better protected are human rights in that country." Coined by Daniel Patrick Moynihan (1927–2003).
-----> I particularily agree with this one
Muphry's law — "if you write anything criticizing editing or proofreading, there will be a fault of some kind in what you have written", first described by Australian editor John Bangsund in 1992. Name derived from Murphy's law.

Skitt's law — a corollary of Muphry's law, variously expressed as "any post correcting an error in another post will contain at least one error itself" or "the likelihood of an error in a post is directly proportional to the embarrassment it will cause the poster."
