“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.”

“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.

“The perils of duck hunting are great - especially for the duck.”

“Don't show it and don't panic. Do like the ducks; on the surface stay calm, and below it paddle lile hell”

“Well, yes, I call it the Expando-Duck. It's perfect if you need a small metal duck. Or a larger metal duck.”
