Stuff I've consumed on purpose? Or accident? I'm going to go with things consumed on purpose.

The strangest thing I've ever eaten was a bison burger. I'm not the most adventurous when it comes to eating. If it's any consolation, I thoroughly enjoyed the burger. As an added bonus, the lack of fats in the Bison meat didn't give me that heavy feeling a regular (and more fat filled) beef burger does after eating.
