Yesterday when the news got out that Hostess intended to shut down, people rushed out to the stores to hoard as many of the endangered snack cakes as possible. Some even put the treasures on e-bay for insane prices. I hate to tell people, but... Even though they are full of preservatives, they don't keep forever. Take it from someone who once opened a sealed package and broke open a very old Twinkie many years ago: seeing green mold in the "creamy filling" isn't a pretty sight. I'm just glad I knew it was very old and didn't bite into it.
