There was once a man who had to do a lot of overnight traveling for his employer. His wife repeatedly ask if she could go with him but he always refused.

Finally, after much nagging, he agreed to take her. They arrived and checked into the hotel. While her husband showered his wife scheduled a wake-up call for six a.m.

At six a.m. the phone rang. As his wife was reaching for the phone the salesman, startled by the ringing, woke up and yelled, "Don't answer that, it may be my wife!"
