Columbia University janitor Gac Filipaj, center, looks on during the Columbia University School of General Studies graduation ceremony, May 13, in New York.
For years, Gac Filipaj mopped floors, cleaned toilets and took out trash at Columbia University.
A refugee from war-torn Yugoslavia, he eked out a living working for the Ivy League school. But Sunday was payback time: The 52-year-old janitor donned a cap and gown to graduate with a bachelor's degree in classics
For Filipaj, the degree comes after years of studying late into the night in his Bronx apartment, where he'd open his books after a 2:30-11 p.m. shift as a "heavy cleaner" - his job title. Before exam time or to finish a paper, he'd pull all-nighters, then go to class in the morning and then to work.
On Sunday morning in the sun-drenched grassy quad of Columbia's Manhattan campus, Filipaj flashed a huge smile and a thumbs-up as he walked off the podium after a handshake from Columbia President Lee Bollinger.
