Very sick Man

A man hasn't been feeling well, so he goes to the doctor to get a checkup. Afterward the doctor comes out with the results. "I'm afraid I have some very bad news," the doctor says. "You're dying, and you don't have much time left." "Oh, that's terrible!" says the man. "How long have I got?"

"Ten", the doctor says sadly.

"Ten?" the man asks. "Ten what? Months? Weeks? What?!"

"Nine...eight..."
