Cheech and Chong are a comedic duo consisting of Richard "Cheech" Marin and Tommy Chong, who gained fame primarily in the 1970s and 1980s for their stand-up routines, comedy albums, and films which often centered around counterculture themes, marijuana use, and satire of the social and political issues of their time.

Tommy Chong, who is of Chinese and Scottish-Irish descent, played the role of the spaced-out, hippie character, while Cheech Marin, who is of Mexican descent, played the streetwise, cynical character. Their humor often revolved around their experiences as hippies, their adventures with drugs, and their observations of American society.

Their most famous films include "Up in Smoke" (1978), "Cheech and Chong's Next Movie" (1980), and "Nice Dreams" (1981), among others. They also released several comedy albums, including "Cheech and Chong" (1971) and "Los Cochinos" (1973), which won a Grammy Award for Best Comedy Album.

Cheech and Chong's brand of comedy became iconic and influential, particularly within the realm of stoner culture, and they remain cultural symbols of the era in which they rose to fame.
