George and jury duty

George was a pirate, but he wasn’t a very good pirate.
Pirate ships don’t get regular mail service, but somehow George got a letter.
“Jury duty,” George growled.
Three weeks later, George was taking off his boots and hat, and setting his swords into a plastic tub.
“Are these real?” said the security guard.
“The letter said business casual,” said George, smiling. “Otherwise I’d have brought all my daggers and flintlocks.”
The guard looked at George’s letter, entered a code in his terminal, and said “Not of sound mind, exempted.”
George gathered his stuff and went back to the ship.
