A fresh 2nd Lt. gets assigned to a base as an assistant to the base General, and is feeling pretty good of himself, as he is an Officer and has a "cooshy" job. He is setting up his office and hears a knock on the door, and wanting to show off he picks up the phone and says, "Enter!" and thus a Sergeant walks in and stands at attention, the Lt glows with pride and speaks into the handset and says, "Thank you for your compliments General, I'm sure I'll get acclamated quickly." And hangs up, thinking he has just put the Sergeant in awe, he then looks at the Sergeant and says, "What can I do for you Sergeant?'' the Sergeant simply replies, "Nothin' Sir, I'm just here to hook up your Phone."
