My dad told me that when he went to college, there was a girl who was a real jerk and a snob to all of the people in the dorm. So when she went off for Christmas vacation, my dad and his friends caught a wild duck, and snuck into her room through the window. They left the duck there along with 2 loaves of bread (so the duck wouldn’t starve). When she came back, her room was covered in duck poo.
