Bad Eggsperiences

Beautiful woman with grimace beacuse of bad smell. Isolated on white.
(I apologize.)
My worst-ever egg-experience was the result of running short mid-baking. I dashed down to the nearest shop – one I seldom visited – and bought a dozen. Only to discover, when I got home, that four of them were rotten!

What’s the worst bad-egg experience you’ve ever had? Horrify us all!
