$1 Million dollars is a lot of money and with these options you're risks are: overdoing a pleasant snack (onion), discovering a new delicacy (century egg), an unpleasant flavor and texture (grub), or like twenty cumulative minutes of fiery pain (carolina reaper).

For $100, none of these are worth it unless we're allowed to prepare them in some sort of dish. For $1000, I'll eat a raw onion. For $10,000, anything but the grub, even all three.

For $1 Million? I'll eat all four of these, raw (possibly wriggling), and ask for seconds, if required. I'd be a fool to do otherwise.
