They’ll Do It Every Time

was a single-panel newspaper comic strip, created by Jimmy Hatlo, which had a long run over eight decades, first appearing on February 5, 1929 and continuing until February 2, 2008.

The title of the strip became a popular catchphrase, still used today by many people who have no idea of its origin. Hatlo, a sports cartoonist, created the panel to fill space on the comics page of the San Francisco Call-Bulletin. Hatlo kept producing the panel, and before long readers were sending fan mail. The feature proved so popular that it was eventually syndicated by King Features Syndicate beginning in 1936, with a Sunday panel added on July 4, 1943.
