I have four of these, With matching extremities. They can do many things, And hardly ever bring me pain. Unless I stick them with a pin, Or burn them sometimes when... What is it that I can wiggle at will? And use in other means still?
Four jolly men sat down to play, And played all night till break of day. They played for cash and not for fun, With a separate score for every one. When it came time to square accounts, they all had made quite fair amounts. Now, not one has lost and all have gained - Tell me now, this can you explain?
The four jolly men are members of an orchestra hired to play at a dance.
