To prevent myself from going into a deep depression if that ever happened, I would:
Call any broker and offer to buy 1,000,000,000 shares of DJIA stock for 50 cents
Use/charge my electronics on an illegal, homemade circuit (the cops would'nt care anymore)
Put parent's bills to more immediate practical use (i.e. use as toilet paper)
Write tender, touching message in homework assignment (like "Shove this shit up your own fucking ass you cunt-licking dick!!!")
What would YOU do yourself to cope with a nuclear war or great depression?
