A man went to his lawyer and told him, "My neighbor owes me $500 and he doesn't want to pay up. What should I do?"
"Do you have any proof?" asked the lawyer.
"Nope," replied the man.
"Okay, then write him a letter asking him for the $1000 he owed you," said the lawyer.
"But it's only $500," replied the man.
"Precisely. That's what he will reply and we will have the proof we need to nail him."
"I'm beginning to think that my lawyer is too interested in making money."
"Why do you say that?"
"Listen to this from his bill: 'For waking up at night and thinking about your case: $250’."
