Sam had been in the computer business for 25 years and was finally sick of the stress.  He gave up his job, and bought 50 acres of land in Montana as far from humanity as possible.  Sam saw the postman once a week and got groceries once a month.  Otherwise it was complete and total peace and quiet.  After six months or so of almost total isolation, as he was finishing dinner, there came a knock on his door.  He opened it, and there was a big, bearded Montanan standing there.   "Names Enos.  Your neighbor from six miles over the ridge.  Havin' a party Saturday.  Thought you might come."  "Great," says Sam, "after six months of this isolation, I'm ready to meet some of the local folk.   Thank you!"  As Enos is leaving, he stops... "Gotta warn ya, there's gonna be some drinkin'."  "Not a problem," replies Sam, "after 25 years in the computer business, I can drink with the best of them."  Again, as he starts to leave, Enos stops.  "More'n likely gonna be some fightin' too."  Damn, Sam thinks... tough crowd.  "Well, I get along pretty well with people.  I'll be there.  Thanks again."  Once again as he is about to leave, Enos turns from the door.  "I've seen some wild sex at these parties, too."  "Now THAT certainly isn't a problem," says Sam.   "Remember, I've been alone for six months!  I'll definitely be there!   By the way, what should I wear?"  Enos stops in the door again and says "Whatever you want.  Just gonna be the two of us."
