G. K. Chesterton (1874-1936)

"You say grace before meals. All right.
But I say grace before the play and the opera,
And grace before the concert and the pantomime,
And grace before I open a book,
And grace before sketching, painting,
swimming, fencing, boxing, walking, playing, dancing;
And grace before I dip the pen in the ink."
