John Kennedy actually said...

"So, Mr. President, I don't think that we will travel any place where our welcome will be more heart-warming, and where we will leave with greater appreciation."

"So I come here today to express our warm feeling of friendship, with great sincerity, to the people of this country."

"And I hope in this way to give some slight indication of how grateful I am to all of you for making us feel so much at home."

"We have come to this open field today to join in making this a better dwelling place for men."
