Question of the Day

What is the worst thing you've ever deliberately eaten?

As opposed to, you know, accidentally getting something gross in your mouth.

And by worst, I just mean taste-wise, or texture-wise. Not cooked right, spoiled, salt used instead of sugar, didn't guess it would taste like THAT, forgot an ingredient, that sort of thing. Let's stay away from commentary that others delicacies outside of one's own culture, i.e. don't treat "gross" and "weird to me" as synonymous.
