For some strange reason you are in a bus with friends (internet friends count too). Suddenly the bus plunges halfway off the edge of a bridge and you are knocked to the back, and the door at the back is flung open. The impact knocks some people in the bus out, and the seatbelts are locked in for the onces that are conscious. You can run down to the front of the bus and save one person, and unless you come up with an genius plan to save more, going back will result in the death of everyone in the bus. Including you.
Some rules; Please specify who is on your bus. Everyone you hold close, and basically everyone you care about is on the bus. You can have internet friends on the bus as well. If you have an ex, s/he is on the bus. boy/girlfriends too, etc.
If anyone can find a way to save everyone in your bus, they receive a cookie. Plus the knowledge of how to save everyone you care about in an accident.
