One day at the court of Charles II, Isaac Barrow (then serving as the king's chaplain), encountered the Earl of Rochester, who had once called the clergyman "a musty old piece of divinity." "Doctor, I am yours to my shoe-tie," the Earl declared with a sarcastic bow. "My lord," Barrow replied, "I am yours to the ground." "Doctor, I am yours to the center." "My lord, I am yours to the antipodes." "Doctor, I am yours to the lowest pit of hell." "And there, my lord," said Barrow, quickly turning on his heel, "I leave you."
