A father had 3 sons. He raised them to become good people. 

One became a lawer, the second one a priest and the third one a banker.

When the father was about to die, he ordered his sons putting each one 10.000 bucks in his coffin. Thus he hoped to see from heaven whether his sons are not greedy.

He died and was laid out in a coffin. First the priest came, wept and put 10.000 bucks in the coffin. Then came the lawer, spoke a silent prayer and put 10.000 bucks in the coffin also.

After hours finally came the banker and gave his dead father a kiss. He was alone with him, so he took the 20.000 bucks and put a check over 30.000 dollars in the coffin saying: dad, thy will be done!
