Lunch gone horribly wrong

I made a couple of ham sandwiches for lunch. The ham was a little old, but it smelled okay, didn't feel slimy, so I figured "What the hell." So I grabbed some out, split it between two sandwiches, and began to eat.

I ate one sandwich and took a couple bites of the other, but I was full. So I opened it up to feed the ham to the waiting cats. But wait -- what's this? I looked more closely at the ham I hadn't eaten, and one whole edge of it was a sickly green. Luckily it was on the opposite side of the part I'd eaten, but still...

So I threw it out, and now I'm waiting to see if I get sick of the ham I did eat. I don't think I will, but you never know. I'll be sure to post all the dire details.
