Kill myself as many ways as I could think of
Largest killing spree the world has ever seen. How could they stop me?
Kill all dictators.
Jump from the tallest building in the world..just to see what it feels like..
That seems like a rip off ( Immortal, just for a day though bro ) lmfao, probably do what Peter Griffin did on family guy, make all kinds of crazy bets, like i bet you guys 1000 bucks i can survive jumping off a skyscraper, or a bullet to the head, and make all kinds of money lol
If I was immortal and could feel no pain for one day, I'd swim in the crater of an active volcano. Just so I can say that I did.
Nothing that would get me killed tomorrow.
