An Army Sgt. Major walks into a whorehouse and approaches the madam and
says, "My name is Sgt. Major Dick and
I'm here for a woman!" The madam immediately escorts the soldier upstairs
and selects the best girl they have for him. Sgt. Major Dick immediately
disrobes and is standing with his hands on his hips while he looks at the
prostitute awaiting him on the bed. He then says, "My name is Sgt. Major
Dick, been in the Army thirty years, and I'm a master of my mind and body,
DICK, ATTEN-HUN!" Immediately, his penis becomes fully erect. The prostitute
is in awe and asks him how he can do that. 
 
The Sgt. Major replies, "Like I said, I've been in the Army thirty years,
and I'm a master of my mind and body, DICK, AT EASE!" His penis immediately
goes limp. The prostitute still can't get over the control he has and asks
him for another  demonstration.
 
The Sgt. Major says, "I'm a master of my mind and body, DICK, ATTEN-HUN!" (a
raging hard-on once again), and
he follows this display of prowess with the command of, "DICK, AT EASE!"
(His penis goes limp once again).
 
The prostitute still can't believe her eyes and asks for the demonstration
yet again. The Sgt. Major shouts, "I've already told you honey, I've been in
the Army thirty years, and I'm a master of my mind and body, DICK,
ATTEN-HUN!" His penis becomes immediately erect, and then he gives the
following command, "DICK, AT EASE." 
 
The Sgt. Major looks down, and to his amazement, his penis is still hard. He
then says, "Apparently you didn't hear me soldier, DICK, AT EASE!" Once
again, his penis is still fully erect. The Sgt. Major is now fuming, and
says, "I'm going to tell you one more time, DICK, AT EASE!" No luck, his
penis is still hard. 
 
He yells, "God damn it!!!", and moves to the side of the bed and starts to
masturbate vigorously. The prostitute asks, "What the hell is going on?" The
Sgt. Major replies, "This soldier disobeyed a direct order, and I'm giving
him a dishonorable discharge!!!"
