Whenever you’re called on to make up your mind,
     and you’re hampered by not having any, 
the best way to solve the dilemma, you’ll find,
    is simply by spinning a penny.

No — not so that chance shall decide the affair
     while you’re passively standing there
moping;
     but the moment the penny is up in the air, 
you suddenly know 
     what you’re hoping.
