YouTube - CHEECH AND CHONG - UP IN SMOKE
Tommy Chong plays Anthony Stoner , a jobless hippy who is kicked out of home by his father and manages to trick Pedro (Cheech) into picking him up off the side of a highway by posing as a woman with large breasts. They both share a large joint (Spliff) (which Chong's character says is made with "labrador", marijuana and dog feces, due to his dog having eaten his stash) and are arrested when a police officer discovers them to be stoned. After their subsequent trial (where they get off on a technicality when it's discovered the judge is drinking vodka), they are released, and in an attempt to procure some marijuana they visit Strawberry (Tom Skeritt), Pedro's cousin. They narrowly escape a police raid on Strawberry's house, but are soon deported to Tijuana by the Immigration and Naturalization Service, together with Pedro's illegal immigrant relatives (who just want a free ride to a wedding).
In order to get back to the United States, they arrange to pick up a vehicle from Pedro's uncle's upholstery shop, but arrive at the wrong place, a marijuana plant, and end up unknowingly involved in a plot to smuggle a van constructed completely out of spray-on marijuana from Mexico to Los Angeles, with the inept police narcotics unit hot on their heels.
Along the way, Cheech and Chong narrowly avoid arrest despite, at one point, being pulled over by the police (luckily for them, the officer gets high from the smoke coming from their van), and pick up two women, who convince them to perform with their band, Alice Bowie, at a Battle of the Bands contest. The film concludes with Cheech and Chong winning the contest, and a recording contract, with a performance of their song "Earache My Eye".
