This Skit is meant for Boy Scouts, Webelos scouts.
Decide for yourself if it is appropriate for your younger scouts or not.

3 scouts

Scout #1 walks across the stage and suddenly grabs his chest and collapses at center stage.

Scout #2 and #3 enter, talking about how excited they are about completing their CPR, First Aid, Lifeguard, ... tarining.

They see Scout #1 and stop.
They rush over and check the person for response.
Scout #2: Are you ok? (shaking his shoulder)
Scout #2: (to Scout #3) Call 9-1-1, he's not responding.
While #3 makes a quick pretend call, #2 listens and feels for breath and signs of life. There are none.

Scout #2 starts fake chest compressions while #3 counts them to 15.
Scout #3: Switch!

All three scouts switch positions. #3 lays down. #2 does counting. #1 does compressions.
