Mind reading so I could know what the wife is thinking. (well only sometimes)
Teleportation so I can get around the world to meet all these sexy lady's that want sex
My super power would be to banish the world of stupid people. Why? Because those bastards are trying to take over.
Since I am bisexual, I wish my super powers to turn myself back and forth between a woman and man. That would be fun. Just think of all the possibilities. They are endless.
