Beta Alpha Psi
  
The fraternity where we spent the best years of our lives. Betas Rule!
Actually, this might be the fraternity where you're least likely to have the best time of your life. Beta Alpha Psi is an honor club for accounting, finance, and information systems. Their Christmas partiers are by far the best audited in the country. It was founded in 1919 and currently has more than 300 chartered chapters.
To join, a college student needs to be majoring in accounting, finance, or information systems, and maintain a minimum GPA level. Former members include Arthur Anderson, founder of the accounting firm Arthur Anderson (good thing he wasn't named "John Fraud"), and William Andrew Paton, founder of The Accounting Review.
On a related topic, the fraternity Sigma Chi has Drew Brees and Brad Pitt as alumni. Just something to keep in mind when choosing your fraternal organizations in college.
