From the New Yorker interview with Fran Lebowitz:
Q: One thing that’s been going around is this idea that Shakespeare wrote “King Lear” while he was under quarantine for the bubonic plague, as a way of inspiring people to use their time productively. Have you felt any of that pressure?
A: Other people have tried to put that pressure on me. For instance, I’ve already read and heard this thing about Shakespeare fifty times. I’ve heard it from writers, and I’ve had to point out to them, “You are not Shakespeare.”
Well, that settles that. 🙂
