A priest goes into a barber's shop sits down, gets a good haircut, thanks the barber, and asks how much he owes him.
The barber says, 'Father, you're a holy man, a man of the cloth there is no charge to you.'
The priest blesses the barber and says, 'Thank you very much' and goes about his business. The next day, 10 gold coins magically appear on the barber's doorstep.
A few days later, a Buddhist monk goes in for a shave and a shine, and when the time comes to pay the barber says, 'No money, please, you're a spiritual leader, a man of the people, it's on the house.'
The next day, magically appearing on the doorstep are 10 magnificent rubies.
The following week a rabbi comes in, gets a haircut, goes to pay and the barber says, 'No, Rabbi, you are a learned man, a wise man, I can't take any money from you, go in peace.'
Then the next day, the barber opens his shop to find 10 Rabbis waiting for a haircut.
