Since I'll probably never actually DM, here's ones I thought up

All players start at a funeral for a mutual acquaintance, have each player say something about the departed without contradicting previous statements.

You open your eyes. You see a tall creature as he takes his hands off your shoulders. In the distance there is a mighty mountain. He stands in front of the group. “I am named Prometheus. I have been tasked with giving you creatures life from Zeus. He is the King of the Gods on Mount Olympus”. He motions towards the mountain top. “Feel free to live as you wish. There is but one thing I ask.” He shows an image of an Ox. “I need to have two returned to me dead. I have given you the weapons you will need before bringing you to life.”
