“Gurnemanz is still not absolutely certain that Parsifal is pure and a fool, as he makes the decision to lead Parsifal to the castle of the Graal, for Gurnemanz sang after they both had walked a while: Now pay attention, and let me see, if you are a fool and if you are pure …!”

“You can't argue with the fools in the world. It's better to let them have their way, then trick them when they're not paying attention.”

“Because you can't argue with all the fools in the world. It's easier to let them have their way, then trick them when they're not paying attention.”

“Fool me once, shame on you. Fool me twice, shame on me. Fool me three times, shame on both of us.”

“And only God who makes the tree
Also makes the fools like me. But only fools like me, you see,
Can make a God, who makes a tree.”

“Fool me one time, shame on you. Fool me twice, can't put the blame on you. Fool me three times, fuck the peace sign. Load the chopper, let it rain on you.”

“To let a fool kiss you is stupid,
To let a kiss fool you is worse.”

“Now and then there's a fool such as I am over you.
You taught me how to love
And now you say that we are through.
I'm a fool, but I'll love you dear
Until the day I die
Now and then there's a fool such as I.”

“I made such a fool of myself,” she lamented.
“Love does not make you a fool.”
“He didn’t love me back.”
“That does not make you a fool, either.”
“Just tell me …” Her voice cracked. “When does it stop hurting?”
“Sometimes never.”

“The great pleasure of a dog is that you may make a fool of yourself with him and not only will he not scold you, but he will make a fool of himself too.”
