Oldie, but a goldie

A man found a magic genie who would grant him one wish. The man said to the genie,” I wish that I had a non-stop bridge from here to Hawaii."
The genie said,” I’m sorry, but that's going to be very hard. Do you have another wish?"
The man answered, "Of course! I want the power to understand all women."
The genie thought for a minute. He replied, "How many platforms did you want on that bridge?"
