Three go, out (or 2 if there are only 4 Cubs). 
 Those
remaining decide on an action to be performed. 
 Suppose
they think of " trip " they tell the other side that it rhymes
with " hip ". 
 The Cubs come in and act whatever is
agreed upon, i.e. skip, rip, etc. 
 They are hissed when wrong
and clapped when they get the word right.
