From Stoppard’s Rosencrantz and Guildenstern Are Dead:
We’re more of the love, blood and rhetoric school. Well, we can do you blood and love without the rhetoric, and we can do you blood and rhetoric without the love, and we can do you all three concurrent or consecutive. But we can’t do you love and rhetoric without the blood. Blood is compulsory. They’re all blood, you see.
End quote.
