Twinkies last FOR. EVER.

Betcha didn't notice the Twinkie in Wall-e, did ya! Yup. Well, it's a long-held myth that Twinkies last for ever. It interests the best of us, including a chemistry teacher in 1976. Mr. Roger Bennatti "placed it on top of his chalkboard for an experiment to observe decay (or lack thereof) in preserved foods," and it stayed there for 30 years (http://bangordailynews.com). It is actually still at the school where he worked, at George Stevens Academy.
Wanna see?
No?
Sorry! ^.^

As you can probably see, the Twinkie is intact. Even so, I for one, would NEVER eat it. Sorry, but they're simply not immortal. Even Hostess doesn't believe it! They said that the new Twinkies now have a shelf life of 45 days. It is better than the old one, which survived around 25 days, but not everlasting. That's for sure.

Verdict: False... sorry
