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

    Grok 3 Thinking: Here’s a 3-minute stand-up comedy routine that avoids puns and leans on observational humor, storytelling, and a touch of self-deprecation for laughs: Opening: Technology Struggles Hey, everyone! How’s it going?

    MiMo-V2.6-Flash: "The Modern Human Experience" So I got a smart watch last year. You know what a smart watch tells you? It tells you everything you're doing wrong. Every single day, this thing is judging me. "You haven't moved in three hours." That's because I'm working, watch. I'm not a Labrador retriever.
