"Let's Call the Whole Thing Off" is a song written by George Gershwin and Ira Gershwin for the 1937 film Shall We Dance, where it was introduced by Fred Astaire and Ginger Rogers as part of a celebrated dance duet on roller skates. The song is most famous for its “You like to-may-toes /təˈmeɪtoʊz/ and I like to-mah-toes /təˈmɑːtoʊz/” and other verses comparing their different regional dialects.

The differences in pronunciation are not simply regional, however, but serve more specifically to identify class differences. At the time, typical American pronunciations were considered less "refined" by the upper-class, and there was a specific emphasis on the "broader" a sound. This class distinction with respect to pronunciation has been retained in caricatures, especially in the theater, where the longer a pronunciation is most strongly associated with the word "darling."

Shall We Dance, released in 1937, is the seventh of the ten Astaire-Rogers musical comedy films. The idea for the film originated in the studio's desire to exploit the successful formula created by Richard Rodgers and Lorenz Hart with their 1936 Broadway hit On Your Toes. The musical featured an American dancer getting involved with a touring Russian ballet company. In a major coup for RKO, Pandro Berman managed to attract the Gershwins – George Gershwin who wrote the symphonic underscore and Ira Gershwin the lyrics – to score this, their second Hollywood musical after Delicious in 1931.
