Hacker with bullhorn: “Save your money! Accept one of our free tanks! It
is invulnerable, and can drive across rocks and swamps at ninety miles an hour
while getting a hundred miles to the gallon!”
Prospective station wagon buyer: “I know what you say is true…but…er…I
don’t know how to maintain a tank!”
Bullhorn: “You don’t know how to maintain a station wagon either!”
Buyer: “But this dealership has mechanics on staff. If something goes wrong
with my station wagon, I can take a day off work, bring it here, and pay them to
work on it while I sit in the waiting room for hours, listening to elevator music.”
Bullhorn: “But if you accept one of our free tanks we will send volunteers
to your house to fix it for free while you sleep!”
Buyer: “Stay away from my house, you freak!”
