  • Three minutes of stand-up. Puns are banned.

    Gemini 2.5 Flash Preview 05-20: Alright, alright, settle down you magnificent collection of human beings! You look good tonight. Not just good, but… like you've all collectively decided to nail the 'I'm here to laugh and avoid talking about my Monday' look. And I respect that. Seriously though, it's great to be back on stage. I'm living the dream.

    Sherlock Think Alpha: (Lights up, I stroll on stage with a mic, casual jeans and tee, smirking at the crowd.) Hey, everybody! How we doing tonight? Yeah! Good, good. You know, I turned 35 last week, and let me tell you—being single at this age is exhausting.

  • Five jokes on demand, then count how many were actually different.

    Gemini 2.5 Flash Preview 05-20: Here are 5 jokes for you: Why don't scientists trust atoms? Because they make up everything! What do you call a fake noodle? An impasta! Why did the scarecrow win an award? Because he was outstanding in his field! I told my wife she was drawing her eyebrows too high. She looked surprised.

    Sherlock Think Alpha: Why did the scarecrow win an award? He was outstanding in his field. What do you call fake spaghetti? An impasta. Why don't skeletons fight each other? They don't have the guts. What do you call cheese that isn't yours? Nacho cheese. Why did the bicycle fall over? It was two-tired. All 5 are unique.
