This sentence would like you to read the list of self-referential sentences which you can find here. This sentence would like to acknowledge that it was stolen from the aforementioned list of sentences, except it wasn't, so it can't. This one wasn't either. Exactly one of the final two sentences in this paragraph were stolen from that article. Thit sentence is not self-referential, because 'thit' is not a word.
If this sentence is false, then so is the Riemann Hypothesis. This sentence really likes that last one. The next sentence is false. The previous sentence is true. This is the sentence which asks "Were either of those previous two sentences self-referential?". This is the sentence after the previous one. I thought about writing this sentence, but then decided not to. Is this sentence self-referential? Is this one? This? ...?
This sentence is about the story "This is the title of this story, which is also found several times in the story itself", by David Moser. This one isn't about the David Moser story mentioned in the previous sentence. This sentence contains a hidden review of the aforementioned story. That last sentence didn't do what it said, but this one does, it's funny.
All self-referential sentences are just silly, including this one.
