Whats in store for what many consider TV's 'It' couple?  Could Leonard and Penny boldly be going where only one of "The Big Bang Theory's" lovable nerds has gone before and getting engaged?  The fan-favorite couple has certainly been through the ringer, having split when Penny was unable to return Leonard's profession of love, reuniting in "Big Bang's" 100th episode.



Where do you think this relationship should end up?
