A knight and his men return to their castle after a long hard day of fighting.

"How are we faring?" asks the king.

"Sire," replies the knight, "We have been burning and pillaging on your behalf for weeks, sacking the towns of your enemies in the west."

"What?!?" shrieks the king. "I don't have any enemies to the west!"

"Oh?" says the knight. "Well, you do now."
