Just a reply to a Sigma Chi. David Letterman was a Sigma Chi, but i have heard that he got kicked out because of grades. I have heard this from some brothers of SIgma Chi. But when he did his Ball State homecoming special with Biff, SIgma Chi ended up on there. THere flag and lots of their brothers! But he is still a Sigma Chi just a little bit of trivia there for you
