My pick...
A harmless bread bowl is it?
Nope.
I'll tell you it's a fine Italian cheese.
...Okay, who doesn't like cheese?
How about I tell you it is riddled with thousands of live maggots, and is illegal and can only be acquired via the Black Market in the only place that actually eats it?
Gulp...What have I gotten my stomach into...
Yes, this 'delicacy' is Casu Marzu, also known as Italian Maggot Cheese.
You did indeed read that right. The only food on my island is riddled with the live squirming maggots of the Cheese Skipper fly. Tons of the 8mm larva squirm and bury their way into this cheese.
They look like this...
They have a chemical that helps break down this cheeses fat content, causing it to have a gooey pasty texture. When you push down on it, the cheese lets forth a stream of liquid, which in Italy they call lagrima, or 'Tears.'
Said maggots also have the ability to launch themselves 6 inches, so it is recommended you shield your eyes to protect them from flying maggots.
I know what you're all thinking now.
"Hey SLAB, why not just wait until the maggots die before you eat the cheese?"
To which I respond, "That is a novel concept. But once the maggots die...The cheese is now to toxic for human consumption."
So, me and Kobe just ate our first block of Casu Marzu, and it also turns out these maggots are quite resistive to stomach acid, and have powerful mouthhooks.
Our new parasitic buddies will now try to bore through our stomachs and intestines causing sometimes sever lesions and a plethora of other side-effects until they are..."Passed"
Bon Apatite.
