Genie

A guy finds a lamp walking through the desert. When he rubs the lamp a genie comes out and tells the man he has one wish and whatever he wants it will be done! The guy says to the genie that he is afraid of height and wants a bridge built from California to Hawaii. The genie replies that it would take all of his powers to build that bridge, and is willing to make any other wish come true instead. The man says, I wish to know how to understand women! The genie says, so do you want 2 or 4 lanes on that bridge to Hawaii?
