3-4 campers are on stage and they call up an unknowing volunteer from the audience.
They tell the volunteer that they are going to have a mooing contest and these are the rules:
Each person in the group has to yell MOO as loud as they can on the count of three.
Whoever is heard above the rest will win. But you have to yell really, really loud.
You also have to beat your chest with your hands, as this will make you Moo louder.
One camper counts out 1-2-3 and the campers just let the volunteer moo as loud as he can.
