Cheech Marin and Tommy Chong were a comedy duo 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. Cheech played a cholo from Los Angeles, while Chong was a burnt-out "druggie" whose entire life revolved around getting high.

The duo released a number of successful comedy albums, and starred in a series of low-budget films, becoming one of the most successful comedy teams of all time. 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, man" (from their self-titled debut album).
