Pardon the example usage, but given a proper noun that contains punctuation (e.g., the title of a show, *Yu-Gi-Oh!*), how would sentence punctuation be used?

> 2. Yes, I watch Yu-Gi-Oh!.
> 3. I can't believe someone your age still watches Yu-Gi-Oh!!

Are these correct, or should they omit the additional punctuation?
