A man was walking along a California beach, when he stumbled across an old lamp. He picked it up, and rubbed some of the dirt from it...
Suddenly, out popped a genie! The genie said, "OK, so you released me from the lamp... blah blah blah... But, this is the fourth time this week, and I'm getting more than a little sick of these wishes. You can forget about three. You're only getting one wish."
The man sat and thought for a while. He certainly didn't want to waste his one wish... Finally, he said, "I've always wanted to go to Hawaii, but I'm too scared to fly, and I get very seasick. So, how about building me a bridge to Hawaii, so I can drive over there?"
The genie laughed, and replied, "That's impossible. Think of the logistics that would be required to do it. How would the supports ever reach the bottom of the Pacific? Think of how much concrete... How much steel!!! No, you'll have to think of another wish."
The man agreed, and tried to think of a really good wish. He finally said, "I've been married and divorced four times. My wives have always said I don't care, and that I'm insensitive. I wish that I could understand women. To know what they are thinking, and to really understand what they are trying to communicate to me....so
The genie quickly replied, "Did you want that bridge to be two lanes or four?"
