This history teacher just got the gift of a lifetime from his students. They raised hundreds of dollars to buy Thomas Corby tickets to the pricey award-winning musical "Hamilton" as an end-of-year gift. He's been desperate to see the show, entering the ticket lottery every day for four years. Corby had to hold back tears, overjoyed that he’ll finally get to be in the room where it happens. "Hamilton" creator Lin-Manuel Miranda responded to the touching video on Twitter.
