"Now, now my good man, this is no time for making enemies." -Voltaire on his deathbed when asked to renounce Satan.

Here are a few other goodies from Voltaire:

Behind every successful man stands a surprised mother-in-law.

An ideal form of government is democracy tempered with assassination.

It is dangerous to be right when the government is wrong.

(My favorite - might be useful for Iraq)
It is not enough to conquer; one must learn to seduce.

Anything that is too stupid to be spoken is sung.

It is forbidden to kill; therefore all murderers are punished unless they kill in large numbers and to the sound of trumpets.
