This is so weird, because I was just reading this article today:

Here's an excerpt:
Lately it seems that everyone and his or her brother has been going back to school to get an MBA, but the importance of this higher degree is getting diluted, and it’s never really been a guarantee you’ll get that plum executive job.
Believe it or not, the majority of CEOs running major companies in the United States do not have MBA degrees. Research done by BusinessWeek magazine in 2006 found that fewer than one in three executives who hold high level positions in corporate America had an MBA.
