I actually did number 11 once - had to drive to the Jacksonville AFES station to enlist in the Navy, after working a ten hour evening shift. The taste alone will keep you awake.
Had a Navy buddy who would swallow a spoonful of coffee grounds, then drink some water - he said it woke him up quicker! 'Course he also dated fat girls ("Shamu Hunting") saying that even fat girls needed loving. Weird boy, that one.
Got reamed by the Senior Chief one day - I cleaned the department coffee pot and threw out the old grounds - he said I ruined the taste! His dark brown mug was white when he got it.
I once found the guys cleaning age-old gunk off some metal cabinets - using the coffee I had made! It worked. I make the same Navy-issue coffee at work now - I love watching those youngsters buzzing around!
