So two days ago I decided to make some scrambled eggs. I go into the fridge and there are two cartons of eggs. I open the one on top and I immediately see that the shells have a very strange opaque nature, and are far from the solid white that normal eggs are. 

I then take a look at the expiration  and it says oct 2014.

I gag for a moment and toss them immediately, thinking these have been there forever, wondering how on earth the whole fridge didn't smell like death. 

I open the second carton, and boom, normal brown eggs. 

I cook my food, it comes out delicious, crisis averted. 

Fast forward two days. 

I'm going to bed when all of a sudden my mother asks if I've eaten any eggs. I say that I had two for my scrambled eggs and that was it. Then she mentions that it was weird because she has just bought a dozen duck eggs for a special cake she was making, and they had randomly disappeared. She was really worried because it was a special order at the farmers market, which is now out of season. 

I realize at this point that the "spoiled" eggs are her beloved duck eggs, and that the expired packaging was because of the eay they recycle old cartons.  I told her how it had hpened and she was livid.
<bot>: saw some funky colored eggs with a weird shell and a bad expiration, threw them away, and they turned out to be really rare and expensive.
