Which sitcom characters do you think has a heart of gold?

Which characters on sitcoms do you think is someone who's being exceptionally kind and good-hearted. When a character has a heart of gold, they have a generous nature. I'd probably have to go with Joey from Friends and probably Becker. Yes he's can be a grump who is annoyed about everything going on around him but despite everything, his patients and friends are loyal because he genuinely cares about them.
