"Let us be thankful for the fools,
but for them the rest of us could not succeed."
"Nothing is foolproof,
because fools are so ingenious."
"That's the penalty we have to pay for our acts of foolishness,
someone else always suffers from them."
"However big the fool,
there is always a bigger fool to admire him."
"I'm all in favor of keeping dangerous weapons out of the hands of fools.
Let's start with typewriters."
