The quotes from Harvey:
From the cab driver: After this he’ll be a perfectly normal human being and you know what stinkers they are.
From Dr. Chumley: Fly specks, fly specks! I’ve been spending my life among fly specks while miracles have been leaning on lampposts at 18th and Fairfax!
From Elwood: Miss Kelly, you know, when you wear my flower you make it beautiful.
If you want any more, you’ll have to watch it for yourself.
