True story:
New member class at a medium-sized university is running joyfully to their new house.
Members of another sorority catch up with them and grab one of the PNMs and say, "Wouldn't you rather be one of us?" (i.e., we suddenly have a vacancy)
Members then run off with the NM.
Protests to the Greek advisor and national offices and NPC were met with, "Would you have really wanted a member who preferred to be in the other sorority?"
