Amy and Penny couldn't be any more different if they tried.
Amy was a neurobiologist who suffered with low self-esteem while Penny was an aspiring actress who worked as a waitress and loved spending her weekends partying with a large group of girl friends. It came as quite a shock, especially to Penny, when these two became besties. Not quite as shocking as that painting of course!
They learned a lot from each other over the years but they still managed to keep ahold of their individual quirks that made them unique. They never let their differences change their own personalities and beliefs. This is what made them such great friends and so entertaining to watch. They are definitely BFF's for life!
