Originally, I thought this would be an awesome prank to play on people, but then I thought about what would happen if that stranger would go to the police and report you for attempted murder.
Or they actually go through it and you end up in prison for aiding and abetting a murderer.
Or nothing happens and it turns out to be an awesome prank.
The world is weird like that sometimes.
