Don't let your meat loaf.

Me, being clever and thrifty in the supermarket:  "Oh look! Buy one, get one free boneless pork tenderloin! I can make so many quick and yummy dinners with these!"

Me, two weeks later, looking in the fridge:  "Shit! I never did anything with those pork tenderloins!"

Luckily, this time, I caught the err of my ways one day shy of the expiration date.  But I've let meat loaf beyond its "good until" date a few too many times.  Damn those tempting sales.
