Cheech and Chong were just characters. They were a parody of the nonsmoker's worst fears about smokers, and bared little resemblance to what real smokers do. That's why they were funny. The down side is they started a trend of presenting smokers as bungling clowns, and an ignorant public latched onto it. Hallucinating slack jawed slobbering fools who can't hold a job or drive a car are labels we have to fight against. This is not really helping.
