A travelling salesman was about to check in at a hotel when he
noticed a very charming bit of femininity giving him the eye. In
a causal manner he walked over and spoke to her as though he
had known her all his life. Both walked back to the desk and
registered as, "Mr" and "Mrs."
After a three-day stay he walked up to the desk and informed the clerk
that he was checking out. The clerk presented him with his bill for
$1600.
"There is a mistake here," he protested. "I have been
here only three days."
"Yes," replied the clerk, "But your wife has been here a month."
