As he was drilling a batch of recruits, the sergeant saw that one of them was marching out of step. Walking up next to the man as they marched, he said sarcastically: "Do you know they are all out of step except you?"
"What?" asked the recruit innocently.
"I said - they are all out of step except you!" thundered the sergeant.
The recruit replied, "Well, Sarge, you're in charge - you tell them!"
