“Start every day with a smile and get it over with”

“Start every day with a smile” became a common saying by the 1930s. “Start every day with a smile and get it over with” is a jocular one-line saying that has been printed on many images. An article in the Los Angeles (CA) Times on October 22, 1967 credited “Start The Day WIth A Smile (And Get It Over With)” to Emil Reisman, a prolific writer of bumper sticker slogans.
 
The line has frequently been credited since the 1980s to American actor and comedian W. C. Fields (1880-1946), but there’s no evidence that he ever said it.
