Another Bad Physics Joke

This is dedicated to my friend Tom, with whom I suffered as a Teaching Assistance for Physics 101 & 102 Lab during our first year in graduate school:

A man hasn't been feeling well, so he goes to his doctor for a complete 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..."
