Input: Lt. Commander Philip Francis Queeg:  Anyone notice anything peculiar about Seaman First Class Urban ? A shirt - tail hanging out of trousers is , I believe , regulation uniform for a bus boy , * not * , however , for a sailor in the United States Navy . These are some of the things we 're going to start noticing again . Mr. Maryk , who is the morale officer ?
Lt. Steve Maryk: We do n't have _ one _ , sir .
Lt. Commander Philip Francis Queeg: Who , then , is the Junior Ensign ?
Lt. Steve Maryk: Keith , sir .
Lt. Commander Philip Francis Queeg: Mr. Keith , you are now appointed the morale officer . In addition to your other duties , you are to see that shirttails are tucked inside trousers .
Lt. Keith: Aye , aye , sir .
Lt. Commander Philip Francis Queeg: If I see one more shirttail flapping while I 'm captain of this ship - woe betide the sailor ; woe betide the OOD ; and woe betide the morale officer . I kid you not .
