Jack the Bulldog
Jack the Bulldog is the official mascot of the Georgetown University Hoyas athletic teams. Jack has been the name of at least five live Bulldogs since 1962, when the name first came into use, though Georgetown counts seven official bulldog mascots including the two living ones. The current incarnation of Jack is an English Bulldog born in 2013 whose full name is John B. Carroll.
Georgetown Hoyas
Georgetown's fight song is rare among U.S. university fight songs for mentioning other colleges by name. Specifically, it mentions Yale University, Harvard University, Princeton University, College of the Holy Cross, the United States Naval Academy, and Cornell University, who were all rivals of Georgetown in the early to mid-20th century, and mocks their fight songs. In recent years the Hoyas only play Cornell and Holy Cross regularly (in football), and many of these schools no longer use the fight songs that Georgetown's song mocks.
