Who would have thought Howard would ever grow up! Howard: Tell her I'm really sorry. And if she doesn't want to marry me, I get it. But what I really want her to know is the guy that she is really disgusted by is the guy that I'm disgusted by, too. But, that guy doesn't exist anymore; he's gone. And the reason is because of her. So, if this relationship is over, let her know that she made me a better man, and tell her thank you. Penny: Oh my god, Howard! That's the most beautiful thing I've ever heard. And it came out of you.
