Three people die, a Doctor a school teacher and the head of a large HMO, when met at the pearly gates by St. Peter he asks the Doctor what did you do on Earth?

The Dotor replied, I healed the sick and if they could not pay I would do it for free. St. Peter told the Doctor, you may go in.

St. Peter then asked the teacher what she did, she replied, I taught educationally challenged children. St. Peter then told her you may go in.

St. Peter asked the third man, what did you do? The man hung his head and replied, I ran a large HMO. To which St. Peter replied, you may go in, but you can only stay 3 days.
