Wow watch the 27 inches tall 21 year old munchkin do like 40 back flips in a row! [video=youtube;dEe9JOCncOI]http://www.youtube.com/watch?v=dEe9JOCncOI&feature=colike[/video] Sometimes big personalities come in very small packages - like in TLC's new series "Big Tiny" (premieres Mon., Aug. 13, 10 p.m. ET), a new series that follows the world's smallest siblings, primordial dwarves Bridgette and Bradley Jordan. Bri, 23, is the world's shortest living woman at 27 inches tall, and her younger brother Brad, 21, is 38 inches tall. Their dwarfism means they need some extra help getting by, so they still live at home with their mother Christy, a nurse, and older sister Brandi, who jokes that she's the outcast for being average size. Bri and Brad's dwarfism also means that they'll never do some things that seem "normal" to most people like driving (they ride in car seats), taking showers (they bathe in the kitchen sink) or going grocery shopping (they need help lifting a bag of sugar). But their diminutive size doesn't stop them from following their dreams, including participating in sports.
