“There was an accident with a contraceptive and a time machine. Now concentrate!”
“Laughter is the best form of contraception.”
“Accidents are not accidents but precise arrivals at the wrong right time.”
“Everyone has a time machine. Everyone *is* a time machine. It's just that most people's time machines are broken. The strangest and hardest kind of time travel is the unaided kind. People get stuck, people get looped. People get trapped. But we are all time machines.”
“Contraceptives should be used on every conceivable occasion.”
“Consistency is a contraceptive; it prevents the birth of new things!”
