A Short Time to Live
A man hasn't been fealing 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..."

A definition of psychiatrist
A Psychiatrist is just a Jewish doctor who can't stand the sight of blood.
