Two privates (who were roommates) were always getting into trouble. One day,
while being marched up and down the drill field by their first sergeant as punishment
for yet another infraction, the three came upon a latern.
One of the privates pick up the lantern and rubs it. A Genie pops out.
"I will give you each one wish; that's three wishes total," says the
Genie.
The first private says, "I want to be back in my warm dry barracks room,
surrounded by beautiful women with all the pizza and beer I can handle.
*POOF* the first private disappears.
The second private says, "Good idea!" I want to be there also."
Looking at the First Sergeant, the private adds, "and surround our room
with a large wall, so we can't be bothered by sergeants!"
*POOF* the second private disappears.
The First Sergeant says, "I'm very curious. Please tell me more about this
wall."
The Genie explains, "Well, it's about 150 feet high, 50 feet thick and
nothing can get in or out."
The First Sergeant says, "Fill it up with water."
