Murphy's Laws

1.If anything can go wrong, it will.

2.If there is a possibility of several things going wrong, the one that will cause the most damage will be the first one to go wrong.

3.If anything just cannot go wrong, it will anyway.

4.If you perceive that there are four possible ways in which something can go wrong, and circumvent these, then a fifth way, unprepared for, will promptly develop.

5.Left to themselves, things tend to go from bad to worse.

6.If everything seems to be going well, you have obviously overlooked something.

7.Nature always sides with the hidden flaw.

8.Mother nature is a bitch.

O'Toole's Commentary on Murphy's Laws

Murphy was an optimist.

我個人最喜歡這一則，忘了誰說的，好像是一則很老的諺語：

When it rains, it pours.
