I've undertaken the task of reading the famous "FountainHead" by Ayn Rand. Notorious for many things save being a page turner, I am delighted by her consistent offerings of quotes such as this:
(a speaker after receiving a riveting applause)
"I am more touched by this reception than I should allow myself to be. I hope I shall be forgiven for a trace of the vain child which is in all of us. But I realize-and in that spirit I accept it-that this tribute was paid not to my person, but to a principle which chance has granted me to represent in all humility tonight."
Good line to remember when you want a humbling acceptance speech :).
