Quoted for truthiness,
Elwood P. Dowd (James Stewart), Harvey
(1950): "Years ago my mother used to say to me, she'd say, 'In this world, Elwood, you must be' - she always called me Elwood - 'In this world, Elwood, you must be oh so smart or oh so pleasant.' Well, for years I was smart. I recommend pleasant. You may quote me."
