M.U.N.
Model United Nations was a challenging project where you tried to find a solution for a wide known topic, and your solution needs to sound like it came from the country you were assigned to. My topic was LGBT and women's rights, and I played the role of Russia. Russia isn't very LGBT friendly, so our end solution to solving our "gay" problem was to nuke the whole world so that no one can be gay anymore. Our class had a vote, and it was the winning solution. The other one was to have peace or keep all gay people in a shelter, but no one needs a simple solution like that.
