My friends used to play a game called gestapo. One person would hide a hammer, then go and let the other tie them up. The one that tied them up would then use any means necessary to find out where the hammer was hidden. Stuff like candles under their feet or tooth picks under their finger nails. If the guy withstood this for 5 minutes he could then hit the questioner with the hammer as hard as he wanted. If he gave in and told him, then he was hit with the hammer. Kind of lost either way.
