Wow, that's cute! I've never heard that one before.
My favorite DZ song is "Delta Zeta Lamps Are Burning," because it's the very first DZ song I learned when I pledged and it's really easy and I just think it's a good song.
My favorite chant is one that my chapter made up. It goes:
UK, Alpha Theta, give 'em Hell, Delta Zeta!
We're the best, can't you see?
Give 'em Hell, Delta Z!
