Mine was a DG. I totally thought she was a Pi Phi!
When I was a recruitment counselor, my girls all thought I was a KD for the first few days. Scarily at the end they all thought I was an ADPi. The funniest was one who stuck to her guns the whole week and insisted that I was a KD-- she was a legacy to our chapter and her older sis was in my new member class! Not only that but the two lived together and there were photos of me in the older sister's room! Wait-- one more-- one day, I accidentally called the legacy by her sister's name. She was really surprised on Bid Day (she went ADPi like her sis) with our big reveal. You can't make this stuff up.
At UCF we like to confuse the heck out of the new members. For PX reveal, we run out in the wrong jerseys when they announce it is time to learn who's who. I ran out in an Alpha Xi jersey and then changed into my letters for the real reveal.
