"Variation" of the red/blue button thing
This is Berryboy. As you may be able to see, he is blue. Since he is blue he has been forcibly chosen to press the blue button. Every person on earth is asked to press one of two buttons. The red button does nothing. You live. The blue button will allow all who press it to live only if 51 percent of the world's population presses it. Will you put yourself on the line for Berryboy? Apologies for any grammatical errors. English is my first language, but I'm too lazy to proofread this stupid hypothetical.
