This is a skit that I have done a couple of times in the past few years. Scouter Bill Palmer - 1st Port Elgin, 15th Juan de Fuca Scouts in Victoria, B.C.
One person is laying on the floor. Two other people walk up. First person: "Hey this guy is hurt." he goes and checks his heart beat. First person: "No heart beat, help me do CPR" Second person goes down and starts pumping on the chest and the first guy does the mouth blows.
Do this for a little while.
Second person: "I'm getting kind of tired here I think it is time to switch."
First person: "Ok, ready"
At this point the person on the ground gets up, one of the other people goes down and they start doing CPR again.
There you go, this is a good skit to do with leaders.
