MERCUTIO: Nay, gentle Romeo, we must have you dance.
ROMEO: Not I, believe me: you have dancing shoes
With nimble soles: I have a soul of lead
So stakes me to the ground I cannot move.
– William Shakespeare
Romeo and Juliet, Act 1, Scene 4. Mercutio tries to persuade Romeo to dance at the Capulets’ party to forget his lovesick troubles. Romeo responds with a metaphor saying that he is weighed down with a soul made of lead. He uses a pun when he refers to his friend’s "nimble soles" and then speaks to his own heavy "soul."
