Hmmm...I can't think of anything crazy I eat that other people don't. Much of what has been listed doesn't seem that crazy to me.
I will admit though that I don't like liver (although liverwurst is OK, as is pate), cabbage (in almost all it's forms including brussel sprouts and cole slaw; red cabbage is OK), creamed baby onions, okra (especially boiled as it just becomes slimy dreck), and chickens feet.
I've tried various things like tongue, sweet breads, etc and they've all been good even if I don't eat them regularly. I guess I don't think of things like sashimi, eel, kimchi, etc to be weird (maybe because I eat them fairly regularly as I work for a Korean company and Annandale, which is close by, is full of Korean places that we frequent). Octopus is good if prepared properly as Boone said (I've had it well prepared in both Greek and Spanish styles).
Never had any form of blood sausage or anything like haggis. Some of the weird food I found abroad I was not brave enough to try (e.g., starfish, scorpions, silkworm cocoons, various insects). I did try sea cucumber and it was OK.
