"Oops" Humor

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

"How are we faring?" asks the king.

"Sire," replies the knight, "I have been robbing and pillaging on your behalf all day, burning 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."
