英语笑话:Who Was That Man（那男子是谁）

The owner of a small travel agency saw an attractive couple gazing at his travel poster. Suddenly inspired, he ran up and told them his idea. "I'll give you an all-expenses-paid vacation in exchange for appearing in ads endorsing my agency." They agreed on the spot.　　Three weeks later he met them at the airport. While the man checked on their baggage, the travel agent asked the woman about the trip. "The food on the cruise ship was wonderful," she said, — and flying the Colorado was a thrill. But I do have one question. Who was that man I had to sleep with every night?"
