Have everyone sit in a circle with one less chair. One person stands in the middle of the circle and says, “Have you ever…” and then they have to say something they’ve actually done. Warning: This can get a little out of hand if you have unsaved kids or new Christians there. Make sure you enforce the “keep it clean” rule, although I’m more lenient on stuff that’s gross like belching the alphabet or getting a green zit.
So the kid in the middle says “Have you ever…” (example) “…gotten a green zit?” Then anyone who’s ever gotten a green zit has to shout “YES!” and jump up and find a seat that is more than one seat away from the one they were originally sitting in. Then someone else is stuck in the middle and has to say, “Have you ever…” (example) “…dyed your hair blue?” etc, etc.
