I had a sweatshirt with letters that my Owl Pal gave to me on Bid Night (your Owl Pal is a pseudo-big sis that switches from week to week until you get your actual big). When I got it it was like the 5th or 6th Bid night it had been used in. Rumor had it the original owner's mom got it for her when she was initiated, and the patern was pretty ugly, so she decided to pass it along to pledges, who would be happy to wear anything with
CW letters on it!
Also, when I was in school we had to dig through food to find clues to where our big sis was for revealing (although I am sure that is considered hazing now...). Anyway, my little was really healthy, so I made her a salad, with Thousand Island dressing, covered it, and let it sit out all night. It was NASTY! She made that into a family tradition.
