When we pledged, God forbid one of our pins were stolen by a sorority girl or we would have to do something to earn it back from her. Well, my pledge class lost two pins in the SAME DAMN WEEK and we decided to march across campus (in our Oxfords and boxers, no less) chanting "A-L-P-H-A, S-I-G-M-A, Alpha Sig, Alpha Sig, ASA" and once we reached the chapter room, she was serenaded with the two songs that she had previously chosen (which we actually worked our asses off for and made REALLY good!) Ah, memories... The sororities just give the pins back nowadays...
