Lawyer's son
The lawyer's son wanted to follow in his father's footsteps, so he went to law school and graduated with honors. Then he went home to join his father's firm.
At the end of his first day at work, he rushed into his father's office and said, "Father, father! In one day I broke the Smith case that you've been working on for so long!"
His father yelled, "WHAT!!! We've been living on the funding of that case for ten years!"
