Prompts you use to test/trip up your LLMs

I'm obsessed with finding prompts to test the quality of different local models. I've pretty much landed on several that I use across the board. Actual benchmark questions (non-trick questions): Tell me about the history of Phoenix's freeway network (A pass is if it gives a historical narration instead of just listing freeways. We asked for history, after all. Again, testing for its understanding of putting relevant information first.) But it got me thinking about other prompts I could use to trip up models too. I started with the Gemma E4B Thinking model (Q6_K with reasoning enabled.
