Burn Him
You take a container of gasoline and dump it all over Dr. Gero. Then you take out a lighter
and throw it on him. He starts burning up and you believe he will surely die. But then he starts running
towards you. And before you can react, he hugs you and you to start burning. You die but he doesn't, only his skin is burned, the iron under it isn't. Then he quotes, "Don't smoke, it doesn't pay."
