Cheech & Chong are a comedy duo, consisting of Cheech Marin and Tommy Chong, who found a wide audience in the 1970s and 1980s for their stand-up routines, which were based upon the era's hippie, free love, and especially drug culture movements.

The duo released a number of successful comedy albums, and starred in a series of low-budget films, becoming a highly successful comedy team. Their best-known comedy routines include "Earache My Eye," "Basketball Jones," "Santa Claus and his Old Lady," and "Sister Mary Elephant." Perhaps their all-time most famous line is "Dave's not here." (from their self-titled debut album).
