Ok, gentlemen, now let's get to the brass tacks:
1) What's the longest after its expiration date that you've eaten an MRE?
2) How much Imodium did you require?
3) How loudly did your wife say, "I told you so!"
4) How long did you wait before trying it again?
1) Decades. It was part of the "Earthquake food" of the 80s and 90s when my dad was in the military. I stated eating them (to get rid of them, so there was room to replace) in 2004. Probably the oldest was from mid/late 80s.
2) Most of them, none. Only 1 had a funky (-er than usual) taste.
3) No wife.
4) I kept going. Tossed the funky dish, finished the entrees and snacks.
