Women will be able to vote (and watch it go to hell then).
Homosexuality will be legal (and double the chances of some people to get married).
Buggery won't be confined to British nobility (and more lawyers will be born).
Smoking won't be allowed in public places (and tax revenues will fall drastically).
Blacks will be able to ride in the front of the bus (and wear the seats out).
Women will be allowed in the military (and 1 out of 4 infantryPERSONS will carry a Porta-Potti).
The US will have a black president (and the world will come to an end).
The Soviet Union might collapse (and abortion have to take the place of godless communism for the people who love a God they fear).

We're going to have to be very, very careful or we'll be overwhelmed by changes we cannot control and will have consequences wise men will fear.
