"Bridge to Hawaii" joke

A man was walking down the beach one day and tripped over a bottle. Out popped a
Genie!
Then Genie says, "I will grant you one wish."
After a minute of pondering the guy says, "I would like you to make me a bridge
from here to Hawaii because I hate to fly and I don't like boats."
The Genie says, "My God, you know how long it will take for me to grant that
wish? How many people it will take to build it? Make any other wish in the world
except that one."
The guy thinks, then says, "I would really like to understand how a woman's mind
works."
The Genie replies, "Would that be two lanes or four?"
