3 Docs at heavans gate!
Three doctors arrived in heaven. St. Peter asked the first one why he should be let into heaven.

The doctor said "Because I won the Nobel Peace Prize for my work."

The second doctor was a little worried when his turn came.
He said, "I haven't won any prizes, but I've started free clinics and helped those in need for free." St. Peter let him in.

The third doctor said, "I'm responsible for all the HMO's across the United States."

St. Peter thought about it for a minute and said, "OK...
I'll let you in, but only for three days!"

An invisible man is here to see you
Nurse: Doctor, there is an invisible man in your waiting room.

Doctor: Tell him I can't see him now. Next.
