Murphy's Law – If anything can go wrong, it will - is actually one of a series of laws reflecting a pessimistic outlook on life:
If anything can go wrong, it will.
You will always find it in the last place you look.
No matter how long or how hard you shop for an item, after you've bought it, it will be on sale somewhere cheaper.
The other line always moves faster.
In order to get a loan, you must first prove you don't need it.
Anything you try to fix will take longer and cost you more than you thought.
If you fool around with a thing for very long you will screw it up.
If it jams - force it. If it breaks, it needed replacing anyway.
When a broken appliance is demonstrated for the repairman, it will work perfectly.
Build a system that even a fool can use, and only a fool will use it.
Everyone has a scheme for getting rich that will not work.
In any hierarchy, each individual rises to his own level of incompetence, and then remains there.
There's never time to do it right, but there's always time to do it over.
When in doubt, drink.
When in trouble, delegate.
Anything good in life is either illegal, immoral, fattening or deadly.
Murphy's golden rule: whoever has the gold makes the rules.
Nature always sides with the hidden flaw.
A shotgun beats four aces.
In case of doubt, say it loudly.
Never argue with a fool, people might not know the difference.
