Leo Bernard Gorcey was an American stage and film actor, famous for portraying the leader of a group of hooligans known variously as the Dead End Kids, the East Side Kids and, as adults, The Bowery Boys. Gorcey was famous for his use of malapropisms, such as "I depreciate it!" instead of "I appreciate it!"

The Dead End Kids were a group of young actors from New York City who appeared in Sidney Kingsley's Broadway play Dead End in 1935. In 1937, producer Samuel Goldwyn brought all of them to Hollywood and turned the play into a film. They proved to be so popular that they continued to make movies under various monikers, including the Little Tough Guys, the East Side Kids, and the Bowery Boys, until 1958.
