An old and crusty retired Army Master Sergeant....

..... was sitting by himself at a bar when a beautiful blonde bombshell comes in the room.
She noticed the old Master Sergeant right away. She finds him rugged and handsome, and sits down next to him.
"May I buy you a drink?" she asks him. He obliges.
She's obviously interested in him. The blonde says to him "So tell me what you do. You seem to be in great shape for a man your age."
"I'm a retired Army Master Sergeant. I don't do much anymore, besides sit at his here bar every night."
She notices he isn't wearing a ring. "Are you not married?", she asks.
"Never have been. Spent most of my life overseas in combat. The army was my wife, until I left her."
At this point, they hit it off. They strike up great conversation, and continue buying each other drinks. The blonde's inhibitions have obviously lowered at this point, and without hesitation, she asks him another question.
"So tell me, Master Sergeant. How long has it been since you've been laid?"
He takes a long pause and stares in the distance in deep thought. He then says, "1955".
The blonde is shocked. "1955! You have some catching up to do! You and me, in my car, right now!"
They hopped in her backseat and commenced to the roughest wildest time she has ever had.
 She couldn't believe his sexual prowess.
She catches her breath after they finish. She's never felt so good before. Completely amazed, she says to him, "Master Sergeant, you definitely have not lost your touch since 1955. You were amazing!"
He takes a look down at his watch and says "I sure hope like hell I haven't, it's only 2330 now!"
