When I came back after winter break, my dorm's fridge had the most disgusting mold in it ever. I put a towel down and everything and let it defrost over two day and the whole nine yards before leaving, so I thought it'd be OK, but it was just.... vile. Black mold everywhere. I had to run to CVS and buy huge rubber gloves and super strong cleaner and clean it for like, two hours. XDD
