On his way to Mexico to film a movie, actor Larry Hagman had a two-hour layover in Tucson on March 10, 1982. While waiting, Hagman, better known as J. R. Ewing of the popular TV show "Dallas," showed off his anti-smoking device to airport employees. A reformed smoker, Hagman carried a teddy bear-shaped plastic bottle. When he pressed its tummy a ring would pop up so he could blow bubbles. Hagman said it helped when he had the urge to smoke.
