Okie doke.
You've been kidnapped by evil men from an unknown empire. Your hands and feet are firmly bound. They have demolished New York with atomic weapons. They take you into a huge warehouse where, on separate platforms, there are: a rock, an eggplant, a cow and a human being.
High over each platform is a 2 ton iron block held by a steel cable.
The cables go over pulleys and thread down to series of release servos. Each servo is wired to a button in a line in front of a table.
The evil guys take you to the table and tell you:
"Pick two of these buttons releasing two iron blocks. You have thirty seconds to pick two, and only two, of them. If you do not, we will destroy Chicago."
What do you do and why?
I smash the rock and the plant. Cows and humans have feelings, as I do, and I don't like pain. "Feels-good" wins every time, and is Good and is part of the Golden Rule.
