bad advice
Walking past the Royal Courts of Justice one day, a man spotted a friend of his sitting on the steps outside, sobbing loudly with his head buried in his hands.

"What's the matter?"

he asked of his friend, "did your lawyer give you bad advice ..?"

"No - it's worse than that," replied the friend between sobs, " he sold it to me..."

A judge, bored and frustrated by a lawyer's tedious argument
A judge, bored and frustrated by a lawyer's tedious arguments, had made numerous rulings to speed the trial along. The attorney had bristled at the judge's orders, and their tempers grew hot. Finally, frustrated with another repetition of arguments he had heard many times before, the judge pointed to his ear and said, "Counselor, you should be aware that at this point, what you are saying is just going in one ear and out the other."

"Your honor," replied the lawyer, "That goes without saying. What is there to prevent it?"
