A judge was reviewing the criminal history of the defendant in front of him and noticed that there was a five-year gap in which he'd committed no offences.

"How is it you were able to stay out of trouble for those five years?”

“I was in prison. You should know that—you were the one who sent me there.”

“That’s not possible,” said the judge, "I wasn’t even a judge at the start of the five years!"

“No, you weren’t the judge. You were my defence lawyer.”
