Generally, it's okay to be a little "creative" when thinking of examples. Of course, it's better to use a famous example that your grader will have heard of, but if you can't do that, a "creative" example is better than none at all.

Next, I'd recommend looking for three different points to discuss. Sometimes graders might be looking to see that you hit specific points, so the more you bring up, the more likely you'll write what they're looking for. Plus, it's usually easier to write one paragraph about three different topics than three paragraphs about one topic.... if that makes sense!
