"Murphy was an optimist" joke

Murphy was an optimist.

My client(sponsor/customer) doesn`t know what he wants.

Nature always sides with the hidden flaw.

Nature is a mother.

Nature will tell you a direct lie if she can.

Needs are a function of what other people have.

Never argue with a fool, people might not know the difference.

Never ask the barber if you need a haircut or a salesman if his is a good price.

Never be first to do anything.

Never be last.
