“The strong appearance of design [in nature] allows a disarmingly simple argument: if it looks, walks and quacks like a duck, then, absent compelling evidence to the contrary, we have warrant to conclude it's a duck. Design should not be overlooked simply because it's so obvious.”

“When I see a bird that walks like a duck and swims like a duck, and quacks like a duck, I call that bird a duck. ”

“We have a saying in the union: "If a fellow looks like a duck and quacks like a duck and walks like a duck, the possibility is that he is a duck." That is the way with a Communist. If the guy does everything that the party does, the prospects are very good that he is a party member or fellow traveler.”

“If it looks like a duck, and quacks like a duck, we have at least to consider the possibility that we have a small aquatic bird of the family Anatidae on our hands.”

“I do not walk like a duck.”

“In a bull market, one must avoid the error of the preening duck that quacks boastfully after a torrential rainstorm, thinking that its paddling skills have caused it to rise in the world. A right-thinking duck would instead compare its position after the downpour to that of the other ducks on the pond.”

“Death strode away, stopped, and came back. He pointed a skeletal finger at The Duck Man.
WHY, he said, ARE YOU WALKING AROUND WITH THAT DUCK?
"What duck?"
AH. SORRY.”

“I shall never eat duck again. I cannot believe I used to like duck. The duck betrayed me.”

“Good design looks right. It is simple (clear and uncomplicated). Good design is also elegant, and does not look contrived. A map should be aesthetically pleasing, thought provoking, and communicative”

“Design can be art. Design can be aesthetics. Design is so simple, that's why it is so complicated.”
