A traveling salesman checked into a futuristic motel.
Realizing he needed a haircut before the next day's meeting, he called down to the desk clerk to ask if there was a barber on the premises.
"I'm afraid not, sir," the clerk told him apologetically, "but down the hall from your room is a vending machine that should serve your purposes."
Skeptical but intrigued, the salesman located the machine, inserted 50 cents, and stuck his head into the opening, at which time the machine started to buzz and whirl.
Fifteen seconds later the salesman pulled out his head and surveyed his reflection, which reflected the best haircut of his life.
Two feet away was another machine with a sign that read, "Manicures, 25 Cents."
He thought to himself, "why not?" He paid the money, inserted his hands into the slot, pulled them out and they were perfectly manicured.
The next machine had a sign that read, "This Machine Provides a Service Men Need When Away from Their Wives, 50 Cents."
The salesman looked both ways, put 50 cents in the machine, and with some anticipation, stuck his little buddy into the opening.
When the machine started buzzing, the guy let out a shriek of agony. Fifteen seconds later it shut off & with trembling hands, the salesman was able to withdraw his friend . . . now with a button securely sewed on the end of it.
