That drop of blood that’s calm proclaims me bastard,
Cries cuckold to my father, brands the harlot
Even here, between the chaste unsmirched brow
Of my true mother.

– William Shakespeare

Hamlet, Act 4, Scene 5. Laertes says if he doesn’t avenge his father Polonius’ death then he will bring nothing but shame to his and his parents’ honor.
