A GI is stationed in a remote outpost in Alaska. There are no women, and he is horny after a few weeks. So he goes to see his first Sergeant and asks for a pass to go to the nearest town to see if he can find some women. The Sergeant tells him that he can't let him go now, but to look out the window.

"You see that barrel?" the Sergeant asks?"

"Yes," said the GI. The Sergeant tells him to stick his dick in the barrel and he will be satisfied. The GI doesn't take him seriously until a few days later. He goes over to the barrel, sticks his dick in, and is completely satisfied. Happy finally, he goes to the Sergeant to thank him about telling him about the barrel.

The GI asks, "Can I use that barrel anytime I get a hard-on?"

The Sergeant says, "Yes, any day except Tuesday."

"Why not Tuesday?" the GI asked.

"Because that's your day in the barrel," says the Sergeant.
