We wear our pledge pins and ribbons every day until we "get in". All of the national fraternities and sororities have their new members wear their pins every day. The local sororities do ribbons, which they wear every day. The local fraternities, well it's a crap shoot as to what they do. Some carry a brick with the letters on it in their bags, others wear homemade t-shirts...depends
My friend is a in the local that does the brick, and every other day or so, he'd drop his backpack on the floor and break the brick. Which meant a new brick. Finally, the brothers got tired of him breaking the brick, so they got this like 50 lb. piece of wood that was part of a bench in their basement (soaked for 30 years in beer and all that!). He had to carry it in a trash bag because it was too big to fit in his backpack. So, he walks into class the next day with his trash bag and drops it on the floor, and I swear it sounded like he dropped a cannon ball! The professor sayss, "what's that in your bag Charles"? And he says "it's my laundry!" Classic
