Well I've challenged myself to do something like that this year.
Long story but it's kind of a punishment for not meeting an earlier task I set for myself a few years back.
I think the easiest of such things to do would be to eat a headless lizard with the guts squeezed out of it,
but as Bear has said in Aussie episodes, the law in Australia prevents a white man from killing any reptiles
(besides, I have a fondness for them, and a pet Bearded Dragon).
