A guy walks into a brothel and tells the madam he wants six girls for the evening. The next morning, the madam informs the gentleman that there will be no charge. Very happy, he leaves. A few days later he returns, and again tells the madam that he would like six girls for the evening. In the morning, the madam presents him with a bill for $1,000. Confused, the man asks, "I don't understand, on Tuesday, it was free." "That's right," replies the madam, "but on Tuesdays, we're on cable."
