A married business executive had to make a trip to Palm Beach for his corporation. After a few days, he was enjoying himself so much that he decided to stay another week as part of his vacation.

Wanting to share this newly discovered paradise, he wired his bachelor friend, "Take the next plane for a fun week on me. Bring my wife and your mistress."

His friend was quick to wire back, "Your wife and I are arriving tomorrow at 11:30 a.m. How long have you known about us?"
