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, even though occasionally we did lose one. I think I deserve to go to heaven."

St. Peter looked at her file and admitted her to heaven.

The second nurse said, "I worked in an operating room. It was a very high stress environment and we did our best. Sometimes the patients were too sick and we lost them, but overall we tried very hard."

St. Peter looked at her file and admitted her to heaven.

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

St. Peter looked at her file. He pulled out a calculator and started punching away at it furiously, constantly going back to the nurse's file.

After a few minutes St. Peter looked up, smiled, and said, "Congratulations! You've been admitted to heaven ...for five days!"
