Smile, Darn Ya, Smile! is the third title in the Merrie Melodies series, and features Foxy. It was released as early as August 15, 1931. It is directed by Rudolf Ising

This is one of only three Merrie Melodies cartoons to star Foxy; the other two being Lady, Play Your Mandolin! and One More Time. This short is a remake of Trolley Troubles, a Disney short featuring Oswald the Lucky Rabbit in whose creation Harman had once been involved.

For the first time in a Warner Bros. cartoon, the short uses a gag, suggested by Bob Clampett, that has characters from the trolley's parody advertising posters (Smith Brothers and others) come to life and perform a bit of business. This type of gag would become a recurring element across Merrie Melodies.

A segment of the cartoon was featured in 1986 Pee-wee's Playhouse episode "The Gang's All Here."
