When I was living in a dorm for the first three years of my first B.A. One day I was cleaning under the bed (which was...terrifying lol) and found a muffin I had taken from dining hall a few months back. It had not moulded at all after all that time...I swear you couldn't break this thing with a sledgehammer. My friends and I tried slamming it against the wall/floor/with various objects...this muffin would not break. That's some damn good preservatives...
Also have no idea how it got under the bed...lol
