Favreau graduated from The Bronx High School of Science in 1984 and attended Queens College from 1984 to 1987, before dropping out. His friend from college, Mitchell Pollack, said that Favreau went by the nickname "Johnny Hack" because of his talent in the game Hacky Sack. He briefly worked for Bear Stearns on Wall Street before returning to Queens College for a semester in early 1988. He dropped out of college for good (a few credits shy of completing his degree), and in the summer of 1988, moved to Chicago to pursue a career in comedy. He performed at several Chicago improvisational theaters, including the ImprovOlympic and the Improv Institute.\n', '
