A Navy Recruit Is Being Shown Around The Ship For The First Time...

As he is going around the ship with the sergeant, they get to the sleeping quarters. The sergeant says, "This is where you will sleep and get dressed." Before they continue on, the recruit spots a barrel with a hole in the side of it in the corner of the sleeping quarters. The recruit asks, "Sir, what is the barrel in the corner for?" The sergeant replies, "That's for when, um, you get horny. You, you know..." assuming the recruit knew what he was insinuating. "Understood" replied the recruit. "Don't forget," said the sergeant. "You can use that barrel every day of the week except Tuesday." The recruit asks, "Why not Tuesday?" The sergeant replies, "Because that's your turn in the barrel."
