A crusty old Sergeant Major found himself at a gala event, hosted by a local liberal arts college.
There was no shortage of extremely young, idealistic ladies in attendance, one of whom approached the Sergeant Major for conversation.
She said, "Excuse me, Sergeant Major, but you seem to be a very serious man. Is something bothering you?"
"Negative, ma'am," the Sergeant Major said, "Just serious by nature."
The young lady looked at his awards and decorations and said, "It looks like you have seen a lot of action."
The Sergeant Major's short reply was, "Yes, ma'am, a lot of action."
The young lady, tiring of trying to start up a conversation, said, "You know, you should lighten up a little. Relax and enjoy yourself." The Sergeant Major just stared at her in his serious manner.
Finally the young lady said, "You know, I hope you don't take this the wrong way, but when is the last time you had sex?"
The Sergeant Major looked at her and replied, "1955."
She said, "Well, there you are. You really need to chill out and quit taking everything so seriously! I mean, no sex since 1955! Isn't that a little extreme?"
The Sergeant Major, glancing at his watch, said in his matter-of-fact voice, "You think so? It's only 2130 now."
