The anniversary of Howard and Bernadette's first date is approaching, and Howard wants to do something special and romantic for the occasion, namely write a song for her which he wants to perform for her with the help of their friends. This gesture makes Penny come to the realization that with the exception of having sex with him, she does nothing romantic for Leonard ever, while he does romantic things for her all the time. She tries to come up with her first ever romantic gesture to make Leonard feel good. But what she ends up doing doesn't quite have the effect she wants, while romance has been sitting in her closet all along. Meanwhile, Sheldon has been zoned out of all his friends' goings-on while he works on something. That something ends up being a breakthrough, namely the discovery of how to synthesize a new, stable super heavy element. This discovery takes the scientific world by storm. After receiving all this well deserved attention, Sheldon discovers that the attention is not well deserved as he made an error in his calculation based on misreading a table, meaning that he accidentally stumbled across his discovery rather than came by it from a purely scientific standpoint. Sheldon has to decide if his error will make him feel bad about what he nonetheless accomplished.
