The first time I had Thanksgiving with my first wife's family, one of the dishes was blackberry jello with green grapes in it. I was never a big jello fan, but I took some of everything to be polite. I put a fork full in my mouth, bit down, and thought "oh no, something is rancid!" The texture was wrong, too. I was just going to spit it into my napkin when I realized it wasn't rancid, but it took a moment for me to place the flavor. It was a green olive.

That should have been a warning that there was something wrong with that family.
