"That depends on what the meaning of 'is', is." Bill Clinton - The definition of a politician.
Most of my favorites, politically, must be from that Sage of Linguists, Bush, Jr. though. A few of his brighter moments:
"They misunderestimated me." The typical cunning misuse of words. All deliberatically, of course.
"You know, one of the hardest parts of my job is to connect Iraq to the war on terror." Steady now. You don't want to say something people may take the wrong way.
"You teach a child to read, and he or her will be able to pass a literacy test." Brilliant use of words to inspire the children...to not wind up like you.
"I promise you I will listen to what has been said here, even though I wasn't here." Bedazzling the crowd.
"Amigo! Amigo!" ...to the Prime Minister of Italy...oy!
"I'm telling you there's an enemy that would like to attack America, Americans, again. There just is. That's the reality of the world. And I wish him all the very best."
"I guess it's OK to call the secretary of education here 'buddy.' That means friend."
"People say, well, do you ever hear any other voices other than, like, a few people? Of course I do." Some are even in his head!
"I've been in the Bible every day since I've been the president." Insert terrifying music....
now."Yesterday, you made note of my -- the lack of my talent when it came to dancing. But nevertheless, I want you to know I danced with joy. And no question Liberia has gone through very difficult times." Indeed, Mr. President. Indeed.
"There's no question about it. Wall Street got drunk -- that's one of the reasons I asked you to turn off the TV cameras -- it got drunk and now it's got a hangover. The question is how long will it sober up and not try to do all these fancy financial instruments." Elegance. Pure elegance.
"And so the fact that they purchased the machine meant somebody had to make the machine. And when somebody makes a machine, it means there's jobs at the machine-making place." You mean the 'factory'? Was that
so hard to remember?
"I'll be long gone before some smart person ever figures out what happened inside this Oval Office." I imagine they turned the cameras off after a time...out of respect for the disabled.
"Removing Saddam Hussein was the right decision early in my presidency, it is the right decision now, and it will be the right decision ever." You tell 'em!
"All I can tell you is when the governor calls, I answer his phone." Could it be? Is he Benson? He looks different now.
Ok, I'm probably pushing my luck posting these. I simply couldn't help myself.
