This movie starts off with Cheech's car catching fire after the duo siphons gas into a trash can. Chong also tortures his neighbor by revving his Harley indoors with the exhaust pipe blowing smoke into his yard. Pedro teachers Man Spanish...He tells Man that bendejo (asshole) means real good friend. Man tells Pedro a bag of salt is coke. Man gives Pedro his sister's urine sample to wash it down. Then, Chong goes out with Cheech's visiting cousin while Cheech stays home waiting for his girl, Donna. Chong and his cousin go on an excursion which includes a massage parlor, a police raid, the arrest of the hotel clerk (Pee Wee Herman), the living room of a very rich family, a near-riot at the "Comedy House," and finally into outer space!
