'Velociraptor' roams through office

Groupon employees were left scratching their heads back in May 2014 when a dinosaur rambled through their Chicago office. Kristin Cella was there to record the footage, and her Facebook video soon had over 500,000 shares. According to her, “Walking with Dinosaurs stores some of their dinosaur suits in Chicago and Groupon thought it would be fun to bring one in.” Credit: Facebook/Kristin Cella
