White Lies

White Lies is simple. Randomly pick a stone (don't show anyone the color). White stone? You must lie. Black stone? You must tell the truth. Now take a card: "Show the group your foot, then tell them your shoe size." "Tell the group about a scar on your body and how you got it." "What's the best trick you can currently perform on a trampoline?" Who lies? Who tells the truth? Be the first to guess, and win. Let the best lie detector win!
