The most bizzare thing happened today

Our sorority mascot is the squirrel, so we have three little beanie baby squirrels in our chapter room at our house. Today someone went in the chapter room and hung two of the squirrels with ribbon and put plastic bags over their heads. The third squirrel they left upside down in a martini glass with a steak knife stuck in it's head. Then they put sticker eyes on napkins and left them all over the walls. As pranks go, that's pretty twisted. We found sticker sheets of the eyes stashed behind pillows and in a drawer, so I think the culprit was caught in the act, which means it's someone in the house. The eyes are soooo creepy looking.
