Generate 5 jokes. How many are unique?

Gemini 3 Flash Preview68 words
Here are 5 jokes: Why don't scientists trust atoms? Because they make up everything. What do you call a fake noodle? An impasta. Parallel lines have so much in common. It’s a shame they’ll never meet. Why did the scarecrow win an award? Because he was outstanding in his field. What’s orange and sounds like a parrot?

Here are 5 jokes: I asked my GPS to take me to a quiet place. It rerouted me to a library and whispered, “You’re already there.” My Wi-Fi and I had a fight. I told it I needed space. It said, “Fine,” and dropped the connection. I tried to start a band that only plays elevator music.

Gemini 3 Flash Preview673 words
(The comedian walks onto the stage, adjusts the mic, and looks slightly exhausted.) How’s everyone doing? Good? I’m doing okay. I’m at that age now where my body has started making "executive decisions" without consulting me first. Like, I woke up yesterday with a back injury. Do you know how I got it? I slept.

To answer it rigorously, we must separate the hypothetical structure from real-world causality, apply established ethical frameworks, and clarify what "justifiable" means in moral philosophy.
