Examples:

(Mae West in She Done Him Wrong, 1933) - "You must give some time to your fellow men. Even if it's a little thing, do something for others--something for which you get no pay but the privilege of doing it."
(Albert Schweitzer) - "I am so clever that sometimes I don't understand a single word of what I am saying."
(Oscar Wilde)
