Which of the following, spoken by Mercutio as he dies, is an example of a pun?
Lady, by younger blessed moon I swear
Ask for me tomorrow, and you shall find me a grave man
No, tis not so deep as a well
Why the devil came you between us?
Definitely "Ask for me tomorrow, and you shall find me a grave man." because the word 'grave' can mean two things; 1: the place of burial for a dead body; and 2: heavy, serious, or with solemnity
