Have you ever

Setup chairs around a circle - have one less chair than there are people in the game. 

One person then stands in the middle and asks the group a question starting with "Have you ever ...".  It must be something they have done themselves.

For example, if I have been water skiing, I could ask "Have you ever been bungy jumping?". Then every person who has done it (ie. bungy jumped) must get up and change seats with someone else. The person in the middle also goes and grabs a seat. Because there is not enough seats, there will always be one person left in the middle, and the game starts again with the person in the middle saying "Have you ever... etc"
