As for the strangest thing I've ever eaten, I'm not sure. I might've tried fried kalamari once (we got some, don't remember if I had any). I guess I don't eat much I'd consider weird.
Oh, I know a strange thing. I came home from school late. We were having tacos, so I grabbed a plate from the dishwasher and started getting my stuff together (I have a taco salad kind of thing first). After that I made this other thing. There's no name for it, I think; it's like a soft taco, but bigger and with all the stuff folded up in one corner. Alway, before I make it I wipe the plate with the tortilla so leftover taco sauce won't get on the outside. So I made that and was done, so I started putting everything away. It was then that I noticed someone had started the dishwasher- the plate I'd eaten off off hadn't been cleaned yet. EWWWWWWW!!!!!!!!!
There are worse delicacies out there, like Balut for one
I've seen Andrew Zimmern (tv show Bizarre Foods) eat all kind of crazy things, including Balut, but the most disgusting thing was probably the sea squirt. I can't find a picture of it or I'd link it. He said it looks like the huerta (sp?) from Star Trek- I think it looks like a bunch of nasty boils in one big glob.
I've found that whenever I eat a tuna sandwich, my pee always smells of it (about an hour or so after consuming). I find it quite fascinating (I love to see what comes out of my body).
I find that the same thing occurs with me when I eat sugar puffs cereal.
