Going on vacation

A man is talking to his friend and he says: “I’m about to go on vacation, and I don’t know what to do.”
His buddy asks: “Why?”
And the man says: “Well, last year’s vacation was Hawaii. I came back, and my wife was pregnant. The year before that was the Bahamas. I came back, and my wife was pregnant. The year before that was Paris. I came back and my wife was pregnant again.”
His buddy asks: “So what are you going to do differently this year?”
And the guy says: “Well, this year I’m going to bring my wife.”
