Having some audience participation helps break up a Pack meeting. Doing something like a cheer, song, or stunt is especially important if your Cub Scouts have been sitting for a little while. Have everyone stand up, including the parents, and do something funny.
A few years back we had a Cubmaster who really enjoyed audience participation segments. The cornier the better! This is a classic along those lines.
This would also work to help demonstrate the importance of clear communication when giving instructions.
Stick Out Your Tongue and Touch Your Nose
Cubmaster: Everyone stand up! Parents also! Now I want to see how many of you can stick out your tongues and touch your noses.
Most will try to touch their tongues to their noses. It is a very funny sight. After about 30 seconds to a minute, the Cubmaster intervenes.
Cubmaster: You are doing it the hard way. I’ll show you the easy way.
The Cubmaster sticks out his tongue and simultaneously touches his nose with his finger.
My dad did this trick (stick out your tongue and touch your nose) as a Cubmaster, circa 1968. The only problem was there was a kid in my den, Ronnie, who had an extraordinarily long tongue, and he was able to win the contest without the gag ending!
