We’re reading the balcony scene and looking closely at Romeo’s famous monolog (almost a soliloquy) when we get to the second half where he begins comparing Juliet’s eyes to stars:

Two of the fairest stars in all the heaven,
Having some business, do entreat her eyes
To twinkle in their spheres till they return.
What if her eyes were there, they in her head?

“What would happen if that exchange happens? If Juliet’s eyes were replaced by stars and vice versa?”

“Um, she would burn up from the heat of the stars, Mr. Scott,” says Mr. Literalist in the front row.
