Query: Cheech and Chong's Comic Time Capsule

When "Up in Smoke" premiered in September 1978, straight and stoned patrons laughed hysterically at the cinematic debut of Cheech Marin and Tommy Chong. Seen today, the film survives as a period piece - terribly uneven and less amusing with the passage of time. Stacy Keach makes an excellent foil for Cheech and Chong's pot-laced antics, but the duo's albums were much funnier.
