That is based on the question "do they meat the threshold of originality?" https://en.wikipedia.org/wiki/Threshold_of_originality

> The threshold of originality is a concept in copyright law that is used to assess whether a particular work can be copyrighted. It is used to distinguish works that are sufficiently original to warrant copyright protection from those that are not. In this context, "originality" refers to "coming from someone as the originator/author" (insofar as it somehow reflects the author's personality), rather than "never having occurred or existed before" (which would amount to the protection of something new, as in patent protection).

This most often comes into play with graphics works, but is applicable to anything that may be copyrighted.

There are one liners are not sufficiently creative in their creation to warrant copy protection. However, note that this is a very low bar.

The bar is more like "Coke can sue you for wearing a red shirt." That doesn't mean they'll win, but they _can_ sue you.

That's a design patent for trade dress - not a copyright.

I can sue you for disagreeing with me. Tortuous malignment.

Do you not understand how the legal system works?

I couldn't prove tortuous malignment. You haven't accused me of committing a crime or something. I haven't lost income as a result of it. So I wouldn't win, but I could sue.
