Cheech and Chong, the stoner pair who dominated the comedy scene in the 1970s and ’80s and recently reunited for their Light Up America tour, take their place in the hot seat to be roasted by close friends and fellow comedians. The duo made a name for themselves with their drug-laced humor, which kept audiences rolling in the aisles with such comedy routines as “Earache My Eye,” “Basketball Jones,” “Santa Claus and His Old Lady” and “Sister Mary Elephant.” They transferred their success to the big screen with a number of hit movies, like Up in Smoke, Nice Dreams and Things are Tough All Over. After several years working on solo careers, the pair recently hooked up again to take their comedy on the road with an American and Canadian tour.
