Since you used this title for your list, I'm assuming you know that old song called "Smile"...? I knew the song for many years but didn't know that it was written by Charlie Chaplin! The music, anyway, if not the lyrics. It was used in his film "Modern Times" (1940).
Also, your list title is an earworm. ;)
