You throw it back into the sea.
Your fellow beachgoers tackle you to the ground & perform a citizens arrest for littering.
You are sentenced for life without parol & spend the rest of your days picking up trash as punishment for your crime, until you die from pollution related health issues. Sucks to suck i guess.
(sidenote: the prison systems in america are immoral and unethical
& i do not actually support them.)
The End!
