He had kidnapped you, he didn't really want to do anything to you, he just liked seeing the fear on other people's faces, and then he threw them around. He was a public figure known for being practically a saint, so he knew no one would believe he was just a sadist. He leaves two glasses with some unknown liquid in front of him, on the table.

It has two glasses. In one glass there is enough poison to kill any human being in a matter of minutes, in the other there is just water.

He bluffed and smiled sadistically.

I'm feeling lucky today, so you can go first. Try your luck, I'll drink the liquid from the glass you don't drink.
