Lyndon Johnson actually said...

"The world is no longer the world that your fathers and mine once knew."

"It has been wonderful to have you leaders of our country and the great molders of our thought to come here and give me this opportunity to tell you what is in my heart."

"I am the President of the United States, the only President you will have, God willing, until January of next year."

"We have learned this lesson around the world at great cost."
