David Letterman quote controversy

[seksiali]

So, at my school (which shall remain to be unknown) several sororities are getting pretty pissed at one another because they are all trying to claim rights to a particular quote from David Letterman. The three sorotities are Alpha Chi Omega, Chi Omega, and Zeta Tau Alpha. And the quote is "Chi-Os were ideal partners for all occasions. They were discrete, desirable, tactful, polite, and fun... Every mom dreamed of her son coming home with a Chi Omega, a woman's woman." Except that each one has it with their name in it. I am hoping that someone can settle this dispute once and for all and maybe send a link with a clip of him saying it or a copy from a trustworthy source.

Thanks!
