Cheech & Chong are a comedy duo founded in Vancouver and consisting of American Cheech Marin and Canadian Tommy Chong. The duo found commercial and cultural success in the 1970s and 1980s with their stand-up routines, studio recordings, and feature films, which were based on the hippie and free love era, and especially drug and counterculture movements, most notably their love for cannabis.

A double act is a form of comedy originating in the British music hall tradition, and American vaudeville, in which two comedians perform together as a single act, often highlighting differences in their characters' personalities. Pairings are typically long-term, in some cases for the artists' entire careers. Double acts perform on the stage, television and film.
