I found this story on Futility Closet's blog here.
For those of you who don't know Georges Clemenceau, he was a French statesman, journalist, and political activist who was staunchly against the monarchy. He was a total badass: he fought loads of duels, got arrested at least once, and eventually left France for the US when the French government started cracking down on dissidents, only to come back years later and become their goddamned Prime Minister. As I said: badass.
The original post reads:
"On the way to one of his many duels, Georges Clemenceau requested a one-way railway ticket.
"'Isn’t that a little pessimistic?' asked his second.
"'Not at all,' Clemenceau said. 'I always use my opponent’s return ticket for the trip back.'"
