“Six months for what?” I asked.

“Six months for the projectile to encyst before the knee can be opened safely.”

“I don’t believe it,” I said.

“Do you want to keep your knee, young man?”

“No,” I said.

“What?”

“I want it cut off,” I said, “so I can wear a hook on it.”

“What do you mean? A hook?”

“He is joking,” said the house doctor. He patted my shoulder very delicately. “He wants to keep his knee. This is a very brave young man. He has been proposed for the silver medal of valor.”
