Theodore Roosevelt actually said...

"I shall only say how glad I am to be here, bid you welcome with all my heart, and say how thoroughly I believe in you, and that I am a better American for being among you."

"We must go on with the task as we have begun it."

"Today, for the first time in my life, I have seen the greatest of the oceans; I have come across the continent from the Atlantic to the Pacific; from the East to the West."

"I think I was a pretty good American when I came here, but I feel that I am a better American now."
