Bridge to Hawaii

A man walking down the street trips over an old oil lamp. As he picks it up, a genie pops out and says, "I will grant you one wish."

The man says, "I want to live in a mansion in Hawaii, but I'm afraid of boats and planes, so I want there to be a bridge from here to there."

The genie sighs. "That's too much work. Sorry, can't make it happen."

The man says, "Fine, then I want to understand women."

The genie replies, "Would you like two lanes or four on that bridge?"
