PUCK [in Lysander’s voice]: Ho, ho, ho! Coward, why com’st thou not?
DEMETRIUS: Abide me, if thou dar’st, for well I wot
Thou runn’st before me, shifting every place,
And dar’st not stand nor look me in the face.
Where art thou now?

– William Shakespeare

A Midsummer Night’s Dream, Act 3, Scene 2. Puck, who is invisible and speaking in Lysander’s voice, challenges Demetrius to come to him and brands him a coward. Completely fooled, Demetrius accuses Lysander of running away and not daring to face him. This is dramatic irony as the audience are in on the trick.
