Back sometime in the 1980s, one of the students at the Kelly School of Business at the University of Indiana was trying to keep his local student-oriented bar going. He’d been cited several times for underage drinking.

Jim Wolfe, who told this story last Friday at MERC 2009, the entrepreneurship conference at George Mason University, was concerned when he discovered that the student entrepreneur had listed him and his business professor mentor, William Haeberle, as advisors to the bar. Jim, now the Entrepreneur in Residence at GMU, was then a law student teaching in the business school under Haeberle’s supervision. He worried about he and his mentor being advisors to a bar that had been accused of catering to underage drinking.

Haeberle was not concerned, however. He told Jim he knew the student. “Don’t worry about Mark Cuban,” he said, “he’s going to make it. He’s a real entrepreneur.”
