MURPHY'S LAWS

·         If you explain something so clearly that nobody can misunderstand, somebody will.

·         Cars prefer to break down on Saturday.

·         Machines that have broken down will work perfectly when the repairman comes.

·         The lift is always on another floor.

·         Having bath makes telephones ring.

·         If something can go wrong, then it will certainly go wrong.

·         Anything that begins well ends badly.

·         Anything that begins badly ends worse.

·         As soon as you talk about something:

                        if it's good, it goes away.

                        if it's bad it happens.

·          If you start to do something, you always find that there is something else which has to be done first.

·         Most things get worse all the time.

·         If it looks easy, it is difficult. If it looks difficult, it's impossible.

·         However many socks you have, three of them are always the same color.

·         Everywhere is uphill on a bicycle.

·         Officials make work for each other.

·         Those who can, do. Those who can't, teach.

·         Nothing is impossible for the man who doesn't have to do it himself.

·         Everything good in life is either illegal, immoral or fattening.

·         You can always find what you're not looking for.

·         When something breaks down, there are always two things go wrong. You will only find one of them.
