October 1915, until the Hurleys and Stan parted ways. Between 1916 and 1918, he teamed up with Alice Cooke and Baldwin Cooke, who became his lifelong friends, to form the Stan Jefferson Trio. Amongst other performers, Laurel worked briefly alongside Oliver Hardy in the silent film short The Lucky Dog (1921), before the two were a team. It was around this time that Laurel met Mae Dahlberg. Around the same time, he adopted the stage name of Laurel at Dahlberg's suggestion that his stage name Stan Jefferson was unlucky, due to it having thirteen letters. The pair were performing together when Laurel was offered $75 a week to star in two-reel comedies. After making his first film Nuts in May, Universal offered him a contract. The contract was soon cancelled during a reorganisation at the studio. Among the films in which Dahlberg and Laurel appeared together was the 1922 parody Mud and Sand. By 1924, Laurel had given up the stage for full-time film work, under contract with Joe Rock for 12 two-reel comedies.

Laurel was credited for directing or co-directing ten silent shorts (between 1925 and 1927), but appeared in none of these. Laurel's future partner Hardy, however, did appear in three of the shorts directed by Laurel: Yes, Yes, Nanette! (1925), Wandering Papas (1926) and Madame Mystery (1926). Laurel and Hardy Laurel next signed with the Hal Roach studio, where he began directing films, including a 1926 production called Yes, Yes, Nanette (in which Oliver Hardy had a part under the name "Babe" Hardy). It had been his intention to work primarily as a writer and director. The same year, Hardy, a member of the Hal Roach Studios Comedy All Star players, was injured in a kitchen mishap and hospitalised. Because he was unable to work
