“After all, the wrong road always leads somewhere.”

“There's a saying that all roads lead to Ankh-Morpork. And it's wrong. All roads lead away from Ankh-Morpork, but sometimes people just walk along them the wrong way.”

“I don't know of any wrong road to Dictionopolis, so if this road goes to Dictionopolis at all it must be the right road, and if it doesn't it must be the right road to somewhere else, because there are no wrong roads to anywhere. Do you think it will rain?”

“...but most roads I have learned from past experience lead somewhere eventually.”

“Does that mean," asked Mack, "that all roads will lead to you?" "Not at all," smiled Jesus..."Most roads don't lead anywhere. What it does mean is that I will travel any road to find you.”

“Even at the end of the road, read the first sentence, there is a road. Even at the end of the road, a new road stretches out, endless and open, a road that may lead anywhere. To him who will find it, there is always a road.”
