What's the greatest extent (as in the most amount of time) to which you've eaten something past its expiration date with the food still being enjoyable?

I bought a cup of plain yogurt for some naan bread. However do to my natural laziness and the yogurt getting pushed to the back of the fridge I ended actually using it over a year past it’s expiration date. The yogurt looked fine, tasted fine (other than being very tangy) and ended up making some tasty naan bread.
