Cheech and Chong may have been 'bout their weed in the movies, but they say they didn't get high when the cameras were rolling. Remembering a scene from 'Up in Smoke', Tommy Chong says: "We tried one time and we wasted so much film." He says they "were in the car waiting for the cue, camera's rolling and we're sitting there, you know, and neither one of us heard the cue." Cheech and Chong are at the US Comedy Arts Festival in Aspen, Colorado. It's their first public appearance since their act broke up 20 years ago!  Now, they say they're writing two new movies, 'Grumpy Old Stoners' and 'Lord of the Smoke'.
