Two incredibly inedible eggs.

I eat a hardboiled egg every morning with breakfast and keep like seven of them hardboiled in my egg rack so I can just wake up and swing open the fridge and shell one, but when I went to go do that yesterday with one, the hardboiled egg inside had a very pale yellow matte appearance and didn't smell like a normal hardboiled egg, and my finger accidentally went through the egg when peeling it. I tasted a little bit and I immediately got a strong vomit reaction. I came to the conclusion that the egg must have been rotten when I boiled it, and, oddly enough, the second egg was the same way, though the third wasn't and neither was the one I ate this morning, though they were from the same carton.
