Three nurses went to heaven, and were awaiting their turn with St. Peter to plead their case to enter the pearly gates.

The first nurse said, "I worked in an emergency room. We tried our best to help patients, but occasionally we did lose one. I think I deserve to go to heaven."

St. Peter looks at her file and admits her to heaven.

The second nurse says, "I worked in an operating room. It's a very high stress environment and we do our best. Sometimes the patient is too sick and we lose them, but overall we try very hard."

St. Peter looks at her file and admits her to heaven.

The third nurse says, "I was a case manager for an HMO."

St. Peter looks at her file. He pulls out a calculator and starts punching away at it furiously, constantly going back to the nurse's file. After a few minutes St. Peter looks up, smiles, and says, "Congratulations! You've been admitted to heaven

... for five days!"
