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 tell 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."
