Everyone sits in a circle and puts both their hands in front of them, fingers/thumbs up. One person goes first and says "Never have I ever..." and then something they've never done. Everyone who has done that puts one of their fingers down. A hubbub should ensue and hopefully people will start chanting "story! story! story!" or something. Whoever puts all 10 fingers/thumbs down first wins, and has also probably done some pretty crazy stuff.
