GEORGE BURNS From an impromptu singing gig in a candy store at the age of seven, to his enduring partnership with Gracie Allen, to solo stand-up comedy acts into his late 90s, Burns kept American audiences in stitches through most of the twentieth century. Invariably, he smoked his trustworthy El Producto cigars during his act, not because he couldn't afford a more expensive cigar, but because they stayed lit on stage longer than the more tightly packed Havana smokes. "If you have to stop your act to keep lighting your cigar, the audience goes out," he once cracked. The legendary star of vaudeville, radio, TV and film resurrected his movie career in the 1970s with starring roles in The Sunshine Boys and Oh, God! Burns, who lived to 100, credited his 10- to 15-cigar-a-day habit over a 70-year span with not only keeping him spry on stage but also with helping him outlive his physician. "If I had taken my doctor's advice and quit smoking when he advised me to," Burns quipped at age 98, "I wouldn't have lived to go to his funeral."
