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.

-Piet Hein,
Poet and Scientist (1905-1996).
