The Website Travis Most Regrets Showing Me...

StillTasty: Keep it or Toss it?

http://www.stilltasty.com/searchitems/search_page

This is a great website that tells you how long any food will last refrigerated or frozen. There's lots of detail, so pretty much any food you look for is there. They also have a commonly asked questions page, which explains why you shouldn't eat pizza that sat out overnight, when you can refreeze thawed meat.

Now I'm even more vigilant about throwing out the leftovers that are in our fridge, much to Travis-I-once-ate-moldy-bread's dismay.
