"Find your four, now look for the two," Karen Murdock tells Lukas. For the World's Smartest horse it's a simple task to identify the numbered plaques before him. In fact, it's that trick that earned Lukas his recent Guinness World Record. It's hard to believe that just a few years ago this Thoroughbred ex-racer stood starving and neglected in a yard. It was only after purchasing this "project horse" that Murdock discovered Lukas' extraordinary capacity to learn, which lead her to expand his tricks to include discrimination tasks. Lukas' story has been heard world-wide and the beloved gelding is heralded as an ambassador for all creatures in need. His touching journey from a race-track reject to an Internet sensation gives hope to all who feel abandoned or misunderstood. Lukas and Murdock, once a homeless teenager herself, will forever change the way you see the animals in your life. Find out how Lukas' story turned from tragedy to triumph, even in the face of nearly overwhelming odds.
