Nerds and jocks have traditionally been foes, though there is one thing that unites them: their unbridled lust for Mythbusters science geek pinup Kari Byron. An artist and sculptor who grew up in the Bay Area and traveled extensively in Asia, the quirky, engaging carrot-top had no aspirations of stardom until she was asked to help out her pals with a stunt on their new show. As good a sport as she is lovely of face, Kari graciously lent her flawless fanny to the mission and had a cast made of it. A star was born, and viewers can see Kari give a tight-bodied twist to the normally uptight and sexless world of science. In one mam-orable episode, Kari even appeared in a bikini, and her Bunsen burners were absolutely smoking.
