There's an interesting rumor going around about Hostess Twinkies. It states that no new Twinkies have been made by Hostess for years. The Twinkies that you buy at the store were made years ago during a massive overproduction decades ago. The rumor says that this is possible because the Twinkie has indefinite shelf life.

I don't know how these things get started but this is definitely an urban legend. While the Twinkie has an uncommonly long shelf life for baked goods, it will only last about a month.
